ok this is a very confusing one,, 
male 31 very sexually active 
so i left a 2 year relationship and started dating a long time friend of mine,,with in the first month we had sex many times but this one time i had noticed a rather large cut on the left side of my penis shaft it was only alittle painful to touch (obviously its an open cut) wasnt there befor,,so i freaked out and went to the doctors i had every STD test done even went for my hiv/aids blood work all came back clear,,i had the swab test done on the scab of the cut,,now i know if it were herpes it takes some time to show up in the blood and if healing may not show up on the swab culture test,,so i let that heal,,then about a month later i awoke to me jerking off in my sleep and where the skin had healed there were more cuts directly around the rim of the first cut,,(could have been re-opening the cut?) ,, so freaked out again i went back to the doctors but they would not re test me so that healed, i asked my gf who knew what was going on the hole time if she ever had problems,,she had not,,but i told her just to be on the safe side to go get tested as well,,now if i got it from her even if she has no symptoms it still should have showed up on her test after having it for a while,,if she had it that is?..her test came back negitive as well,,so another month later something happened in the same spot it started to get intchy and got progressively worse over two weeks untill i scratched so much it became raw and red i caused about 3 small cuts that scabed over right away ,,in the cases of the cuts right from the begining i never saw them as blisters so never saw any fluid come from them,,and i sought out two other doctors one had told me it was damaged skin and not to masturbate for a while,,the other said it might have been a fungal infection but is sending me to a dermatologist i have noticed that even after healing if i jerk off to much it will start to bother me,,any one got any idea's,,at this point i dont even care ive already gone thru so much,,iam just as lost as the doctors,,in the first two cases there was no pain or symptoms ,,never pain during urination ,, i just wanted to come back with an update,,so since my last posting my symptoms have not gone away,,,its been so constant it started itching back in june !!,,i ve seen the dermatoligiest,,she had mentioned she didn't think it was an std and mentoned that it looked like it was bleeding at one point and gave me some betaderm ointment,,i am going back in to see her for a biopsy in two weeks ,,so i do have a follow up question ,,do you think herpes would effect someone like that i know its different in many people but,, constant? i still haven't even fully healed from the last cut i have gotten a few weeks ago and the itchy and sensitive skin have not gone away,,maybe a day or two here and there but that's about it,,so when it was at a bad point the pulled the skin and noticed that  there was 3 tiny bumps spaced out, touching them directly i noticed these are definitely the cause of the itch and sensitive skin around them and are a little painful to touch or just that sensitive ,,they don't break on there own and i cant even see them unless i pull the skin and get close,,but i did squeeze them to see how easy they would break,,it wasn't easy and they made a snapping noise when i popped them ( i know this is never recomended but its getting to that point i need to do whatever i can to help figure this out),,didn't really notice anything come out of them,,this has been going on for almost a year now,,i have other sexual partners and have been careful using condoms,,but wouldn't it spread to another person it they were touching it alot? because there has been no spreading to other peoples skin that have touched it? ,,god i cant wait for this last test to know what is really going on
