Why do men fall asleep right after sex?

For many women, this must be one of the most annoying facts of men:
"First, the obvious reasons for sex’s somnolent sway: the act frequently takes place at night, in a bed, and is, after all, physically exhausting (often more so for the man than the woman, although this certainly varies). So when sex is over, it’s natural for a guy to feel sleepy.

Secondly, research using positron emission tomography (PET) scans has shown that in order for a person to reach orgasm, a primary requirement is to let go of “all fear and anxiety.” Doing so also tends to be relaxing and might explain the tendency to snooze.

Then there is the biochemistry of the orgasm itself. Research shows that during ejaculation, men release a cocktail of brain chemicals, including norepinephrine, serotonin, oxytocin, vasopressin, nitric oxide (NO), and the hormone prolactin. The release of prolactin is linked to the feeling of sexual satisfaction, and it also mediates the “recovery time” that men are well aware of—the time a guy must wait before “giving it another go.” Studies have also shown that men deficient in prolactin have faster recovery times."

Do nudists walk around with an erection?

How I dared to be bare!:
"NUDISM is not about sex, honest. I've been told this by at least 20 people at Pacific Sun Friends, a nudist camp on the Sunshine Coast. After two days here, I've watched as a lot of mostly middle-aged naked people play minigolf, take nature walks, sunbathe or sit around chatting.



...despite all attempts to keep their nudist haven free from wanton thoughts, one of the most common questions from new (male) nudists is:, 'What if, um, something comes up?'

Jan says: 'We've had single and married males say that even the breeze will cause them to have an erection, but if that happens here, the man just discreetly turns around, or he might just sit down for a while, or put his towel around him.

'Nudists aren't prudes or anything, but you generally don't walk around with an erection. It's one of those unwritten rules.'"

Sexual Prowess of Sumo Wrestlers

Do Sumo Wrestlers and other fat men enjoy sex?:
Comprehensive research into the subject in Japan and Korea indicate that both impede on the sexual performance of men. There are a number of clear physiological reasons for this:

1. A fat man undergoes a process of feminization: hormones in the fatty tissue turn into estrogen the female hormone. That is why obese men - such as Sumo wrestlers - have higher voices and their skin is more delicate.

2. Fat men suffer from health problems, have difficulties maintaining relationships, and suffer from prejudice at work - and on top of all this they suffer from sexual dysfunction. A surplus of female hormones, blockage of blood vessels and possible diabetes, shortage of breath - all enemies of the erection and sexual pleasure.

New study proves non-inferiority of LEVITRA in comparison to VIAGRA for the treatment of Erectile Dysfunction

CNW Group:
"TORONTO, Sept. 19 /CNW/ - Results of a new medical study, launched today at the Congress of International Society of Sexual Medicine (ISSM) in Cairo, Egypt, and published in the Journal of Sexual Medicine (available online http://jsm.issir.org), show that men with erectile dysfunction (ED) and risk factors for cardiovascular disease expressed a treatment preference - 53 per cent preferred LEVITRA(R) (vardenafil) compared to 47 per cent who preferred VIAGRA(R) (sildenafil). This study demonstrated non-inferiority of LEVITRA to VIAGRA for overall preference and achieved statistical superiority to VIAGRA for several frequently used efficacy measures - meaning that LEVITRA is at least as good as VIAGRA, while SEP 2 and 3(*) efficacy shows a superior effect for LEVITRA."

More Belgian men resort to "erection pills"

People's Daily Online - More Belgian men resort to "erection pills":
"The number of men hoping to improve their sexual performance by taking medicine has more than doubled in Belgium in recent years, VRT news reported Wednesday.

Some 4 million tablets, designed to help men either get or maintain an erection, have been sold in Belgium this year, VRT quoted a study by the Institute for Medical Statistics as showing.

The Association of Pharmacists believes that the big increase is due to growing confidence in so-called 'erection pills' among the country's males.

Those who are in their forties are the biggest buyers of pills such as Viagra, the market leader in Belgium. However, an increasing number of younger men are also reaching for the pill box to ensure success between the sheets, the study shows."
