Here's a strange fact: In a scientific study they found that jumping up and taking a shower directly after sex appears to "reactivate" HIV.
-------------------
Cleaning the penis minutes after sex does not wash away HIV. On the contrary it even increases the risk of getting infected.
The team at the Makerere University Institute of Public Health made the research on 2,552 HIV-negative men aged 15 to 29 from the Rakai district, Uganda. 83 % of the subjects told they washed their penises with all sex partners.
They were asked when and how they washed their penises, even if they washed it with or without clothes, at the start of the research and at 6, 12 and 24 months after that. Still, the researchers did not questioned the subjects about the type of used soap, and this is an important issue, as some African soaps are more irritating than soaps coming from other places.
Men who washed within 3 minutes after sex had a 2.3% risk of HIV infection, while those who delayed washing 10 minutes or more had a risk of just 0.4%. Scientists believe that delaying washing means a longer exposure to vaginal secretions, that could be involved in lower viral infectivity.
The vaginal secretions have a low pH (under 7 or acid) and this decreases HIV's survival capacity on the penis, while water has a neutral pH, around 7, increasing HIV's survival and the man's possible infection. "HIV likely needs to be in a fluid to cross the mucosa and infect cells. If HIV-infected fluid dries, its infectivity could decrease.", said co-author Ronald Gray, professor of population and family planning at Johns Hopkins Bloomberg School of Public Health.
Thus, soaking the penis with water reactivates the HIV. "There ought to be a little time left for postcoital cuddling before you go and wash. Don't just finish and jump out of bed.", added Gray.

Now that is interesting!
