I have been dating my boyfriend for 2 years and as far as I know he has never been unfaithful. Shortly after we started dating I got tested for STDs and nothing showed up but I had a bacterial infection and was treated for it. When I went in for my annual check up my doctor said that I had gonorrhea and she treated both me and my boyfriend for it. So I asked her if since that didn't show up the first time would that mean something else wasn't showing up again. Well now a few weeks ago I had what I thought was a big pimple at the very bottom of my vagina kind of off to the side and I popped it and it went away. Well now my boyfriend has sort of the same thing it looks like a pimple or a blister almost and its towards the end of his penis close to his testicles!??! What could this be..is it herpes?! He hasn't really said anything about it like it hurt but I touched it yesterday and he said ouch..so I am guessing its kind of sore.
