Well i just started with my girlfriend having anal sex and nothing happened but about a week later my penis started really itching. It also started itching after a weekend of being in a forest everyday for hours so maybe poison ivy. First I got red itchy bumps around my wrist, then I got a red bumpy rash near my neck which is kinda scabbed now. I also have many mosquito bites. But maybe a day after the rashes on my arm and neck my penis shaft got very itchy were I couldn't stop itching it. I got little bumps on it now kinda like my neck but not so swollen. I've been with my girlfriend for about one year and she has been totally honest with me (I think =\) and she has said she has no STD's. I have had oral sex with her to for over 8 months and nothing like this has happened. The only time I use a condom is when I have sex with her. I didn't use a condom with I have anal sex though. Please someone give me there best bet on what this could be. And I don't think the bumps on my penis have any liquid coming out of them but it might. I can't tell right now.
