that website is f'n trippy if you dig deep enough

Not sure if the Op is true but that website has some interesting reads on it

I think it is true.

it was a study on unprotected sex vs using condoms and was still inconclusive.

Keep in mind the Daily Mail is a tabloid rag about as accurate as the national inquirer - they run all sorts of crazy stories such as cannibal chefs serving human meat in restaurants blah blah blah

More info on the study from the article:

In 2012, the Daily Mail posted an article entitled “Oral sex is good for women’s health and helps fight depression.” This was an example of wishful thinking based on a controversial study from 10 years earlier. The 2002 study from the peer-reviewed Archives of Sexual Behaviour made the bold claim of semen having an antidepressant effect on women. The research was based on an anonymous survey on condom use among female college students, comparing findings on condom use and sexual activity with the results of a standard test of depression. They wished to investigate the hypothesis that semen had an effect on the mood of women and whether hormones found in semen, including testosterone, estrogen, and prostaglandin, could be absorbed through the vagina. The results showed women who engaged in sexual activity without condoms showed less depressive symptoms than those who used condoms and those who abstained from sexual activity altogether. The study concluded by saying that semen absorbed through the vagina may have an antidepressant effect and that it would be interesting to do further studies on absorption of semen hormones from oral or anal sex. The problem with the study itself was that it did not take into account other factors potentially affecting depression, such as whether the women surveyed were in a relationship or their frequency of sexual activity. It also didn’t take into account the possible use of coitus interruptus contraception for those who didn’t use condoms, so the correlation between condom-free sex and the absorption of semen hormones was dubious at best.There is also the possibility that personality characteristics play a part in the non-use of condoms and reduced risk of depression, and that people with “happy-go-lucky” personalities are less likely to use condoms or experience depression. Finally, as the study in question didn’t investigate oral sex at all, the Daily Mail article was likely pulled entirely from one of their journalists’ lurid imaginations
