can someone tell me more about prep?
PrEP means Pre-Exposure Prophylaxis, and it’s the use of anti-HIV medications to keep HIV negative people from becoming infected. PrEP is approved by the FDA and has been shown to be safe and effective at preventing HIV infection.
You can cheek a lt of info here: http://www.whatisprep.org/.
In my opinion is's only for monogamic couple, where one person is infected.
