Private: Blowjob-Less-Known-Facts1 By Dr. Ashok Koparday Best Sexologist in Mumbai in SEX EDUCATION What is “Blow job” or “Fellatio”? Fellatio fellation,[1] is oral sex performed upon the penis. It may be performed to induce orgasm and ejaculation of semen, or it can be used as foreplay prior to vaginal or anal forms of intercourse. Fellatio is commonly referred to as a blowjob.[2] Fellatio is also sometimes referred to as “giving head” or “going down.”[3] Other terms include “sucking dick” and “sucking off.” ADVANTAGE OF BLOWJOB Fellatio is sometimes practiced during pregnancy as a replacement for vaginal sex by couples looking to engage in a sexually pleasurable activity while avoiding the difficulty of vaginal intercourse during the later stages of pregnancy.[4] SAFE SEX – NO PREGNANCY [5] Fellatio does not cause pregnancy; there is no way for sperm from the penis to enter the uterus and fallopian tubes to fertilize an egg. In humans, there is no connection between the gastrointestinal system and the reproductive tract. Sperm is killed and broken down byacid in the stomach and proteins in the small intestine. 1. ^ "Fellation – Definition from the Merriam-Webster Online Dictionary".

Semen Arousal: Its Prevalence, Relationship to HIV Risk Practices
C S & lini ID ca A l f R o e l s Klein, J AIDS Clin Res 2016, 7:2 a e Journal of n a r r DOI: 10.4172/2155-6113.1000546 c u h o J ISSN: 2155-6113 AIDS & Clinical Research Research Article Open Access Semen Arousal: Its Prevalence, Relationship to HIV Risk Practices, and Predictors among Men Using the Internet to Find Male Partners for Unprotected Sex Hugh Klein* Kensington Research Institute, USA Abstract Purpose: This paper examines the extent to which men who use the Internet to find other men for unprotected sex are aroused by semen. It also looks at the relationship between semen arousal and involvement in HIV risk practices, and the factors associated with higher levels of semen arousal. Methods: 332 men who used any of 16 websites targeting unprotected sex completed 90-minute telephone interviews. Both quantitative and qualitative data were collected. A random sampling strategy was used. Semen arousal was assessed by four questions asking men how much they were turned on by the way that semen smelled, tasted, looked, and felt. Results: 65.1% of the men found at least one sensory aspect of semen to be “fairly” or “very” arousing, compared to 10.2% being “not very” or “not at all” aroused by all four sensory aspects of semen. Multivariate analysis revealed that semen arousal was related to greater involvement in HIV risk practices, even when the impact of other salient factors such as demographic characteristics, HIV serostatus, and psychological functioning was taken into account. Five factors were found to underlie greater levels of semen arousal: not being African American, self-identification as a sexual “bottom,” being better educated, being HIV-positive, and being more depressed.

Commentary Unprotected: Condoms, Bareback Porn, and the First Amendment
Commentary Unprotected: Condoms, Bareback Porn, and the First Amendment Bailey J. Langnert ABSTRACT In November 2012, Los Angeles County voters passed Measure B, or the Safer Sex in the Adult Film Industry Act. Measure B mandated condom use by all porn performers in adult films produced within county borders and created a complex regulatory process for adult film producers that included permitting, mandatory public health trainings, and warrantless administrative searches. Shortly after its passage, Vivid Entertainment filed a lawsuit to enjoin the enforcement of Measure B, arguing that the Measure violated their First Amendment right to portray condomless sex in porn. In December 2014, the Ninth Circuit upheld the district court's decision upholding the constitutionality of Measure B. Notably, the mainstream discourse surrounding the Measure B campaign, as well as the legal arguments put forth in the lawsuit, focused exclusively on straight pornography while purporting to represent all porn. As a result, an entire genre of condomless pornography went unrepresented in the discussion: bareback porn, which portrays intentional unprotected anal sex between men. Excluding bareback porn from the lawsuit represented a missed opportunityfor Vivid in its challenge of Measure B. There are several political messages underlying bareback porn unique to that genre that might have resulted in the t The author received a law degree from the University of California, Berkeley, School of Law (Boalt Hall) in 2015.

Gay Men and Barebacking: Radical Or Realistic?

Roberson Prepared for Dr. JoAnn Pavletich ENG 3305 Advanced Essay Writing Fall 2009 Semester Gay Men and Barebacking: Radical or Realistic? Page 1 of 17 By Eric J. Roberson Gay Men and “Barebacking”: Radical or Realistic? By Eric J. Roberson Sex is not a competitive sport, and if you are gay and think it is then you should listen up! “HIV is a serious long-term condition, and young gay men remain the group of young people most at risk” (“UK Same-Sex Relationships 1). Some gay men willfully and deliberately discard condoms in preference for unprotected sex. Regardless of your age, this essay will not convince you on what to do with your “hard on,” but it may help you decide to get tested and to put on a condom before your next casual sexual encounter. Consider these three simple solutions: communication before sex, compassion for others, and condoms for casual encounters. If you happen to be straight and are reading this essay, do not put it down. Straight people who have gay friends may learn about some of the challenges gay men face in leading fulfilling relationships. You may also gain ideas on how to be more supportive. Regardless of your sexual orientation, the goal is to expose how the internet has shaped the practice of barebacking and other mitigating factors that compel gay men to consciously and explicitly eschew condoms during anal intercourse – colloquially known as “barebacking” (Gastaldo, et.

Should Men Worry About Dry Orgasms? a Dry Orgasm?
The Online Resource for Sexual Health Patient Education SexHealthMatters.org is brought to you by the Sexual Medicine Society of North America, Inc. Should Men Worry About Dry Orgasms? A dry orgasm? For men, it sounds like a contradiction, doesn’t it? Men ejaculate semen at orgasm. Doesn’t that make orgasms, by definition, wet? The answer is: Not all the time. Some men reach orgasm – and feel great pleasure from it – but do not ejaculate any semen at all. Or, they might ejaculate a very small amount. This is what we mean by “dry orgasm.” While they might seem a bit unusual, dry orgasms are usually nothing to worry about. They can be a challenge for couples who would like to conceive, but they generally not a health risk. What causes dry orgasms? Men may have dry orgasms for a variety of reasons. Younger men with short refractory periods might have them occasionally. The refractory period is a period of time after orgasm during which a man’s body recovers and doesn’t respond to sexual stimulation. These intervals often don’t last long in younger men. In fact, it can be just minutes before a man is “ready to go” again. And he might climax several times during one sexual encounter. Eventually, however, the well runs dry. A man has a limited amount of semen to ejaculate and if he keeps going, that supply will be depleted. It’s not a cause for worry, though. In a day or two, the man’s body will produce semen to replace what has been ejaculated and he’ll be back to a full supply.

The Persistance of Seminal Constituents in the Human Vagin
Elsevier Sequioa A.A., Lausanne – Printed in The Netherlands THE PERSISTANCE OF SEMINAL CONSTITUENTS IN THE HUMAN VAGINA ANNE DAVIES and ELIZABETH WILSON Metropolitan Police Forensic Science Laboratory, London (Great Britain) SUMMARY The persistence of spermatozoa, seminal acid phosphatase, choline and seminal blood- group antigens in the human vagina after sexual intercourse has been studied and the following results obtained. 1. Spermatozoa were usually found up to 3 days after intercourse and were occasionally found up to 6 days afterwards. Smears without spermatozoa were obtained from swabs taken as early as 28 hours, but remained rare until 2 days after intercourse. 2. Seminal acid phosphatase sometimes remained detectable up to 3 days after sexual intercourse. The test was most useful on swabs taken within 1 day and rarely useful after 2 days. 3. Choline was usually only detectable on swabs taken within 1 day of intercourse and even within this time many negative results were obtained. The probability of positive results declined swiftly after 14 hours. 4. Seminal blood-group antigens were only detected at a useful level on swabs taken within 48 hours of intercourse. The chances of obtaining a positive result decreased swiftly with an increasing time interval after intercourse. INTRODUCTON The persistence of seminal constituents in the vagina is frequently of considerable importance in alleged offences involving sexual intercourse. Interpretation of the tests currently used in this laboratory to determine the presence of semen is often difficult due to variations and contradictions in the published literature. Semen is usually identified by the presence of spermatozoa. There are widely varying estimates of the time that spermatozoa survive in the vagina.
