My bestfriend and I have eachother blowjobs and pretended it was a girl. We did for a period of time when I was in 8th and he was in 7th. Then maybe a little during my freshman summer before my soph year which was his 8th grade summer before his freshman year. I never did anything like that with anyone else. I have a girlfriend now. My friend and i are fine today but we dont talk. I'm a senior now. I HAD a red bump sore on my penis shaft a couple years ago.i did show it my mom and dad but not the doctor there's still a scar there though and I showed my mom that. I also have this rash that comes and goes during summer that's on my hands and feet that I've had for years that the doctor said is contact dermatitus. I've never been tested for stds. I don't wanna tell anyone about me and my friend experimenting not even the doctor. Do u think I have a life threatening std like syphillis or somthing?
Also make sure to do a urethral swab test for bacterial STD's:
Gonorrhea, Chlamydia, Trichomoniasis, UreaPlasma and MycoPlasma.
Finally... I'd abstain from having sex until you have those tests done (especially Syphilis) and should it turn out that you DO have something, inform your current girlfriend AND you previous sex buddy so both can get tested and treated.
From what you described, it could also be nothing really serious, but its better to be safe than sorry.
Rashes can come and go for a variety of reasons, plus I wouldn't be surprised if its a seasonal thing... but just in case you definitely want to have Syphilis checked out along with other bacterial STD's I mentioned as soon as possible.
