Hi, I have had sexual contact with three women over the past few (1-3) months and am worried about possible STD/HIV contraction. I received unprotected oral from all of the girls. I participated in protected vaginal penetration with two of them, of which only lasted a few minutes each time. One girl was an escort (Backpage), one was an asian massage parlor girl, one I met online (Craigslist). I have what seems to be herpes. Bumps on my penis head. However, I have had those bumps for months and after three rounds of STD/HIV testing (all negative) and three separate doctors calling the bumps are normal and not consistent with herpes I let go of the idea. Also, because took it upon myself to dissect a few bumps and none of them produced any liquid, puss, etc. I guess my questions are do you think I should be tested a 4th time for STDs/HIV? Is there a good chance I may have caught something, or are chances slim. I went through an awful spurt in college for two years where I saw escorts, etc. often. I had the three tests aforementioned performed after I had stopped (or so I thought so), which yielded the negative results. Thanks for any and all help.
