Hello,
I have only had sex with one girl in my life thus far and it was with my girlfriend of a year and a bit. When we broke up, I fooled around with a few girls, but only resulted in oral sex as I wasn't really ready to have sex with someone different so soon. But after a few months a bump appeared about half way up my penis on the back side. It is red and its shape changes, it grows and shrinks. It also releases a white pus occasionally. I've had it for about 2 months, been really hoping for it to just go away. I haven't fooled around with anyone since its appeared as its quite worrisome. I don't think my ex could have given me anything, we had both been tested in november and everything was fine, we broke up in january.
What could this be? I've looked at pictures of herpes and it just doesn't look at all the same, but maybe that's just me freaking out about the possibility. Any ideas would be greatly appreciated, including possible treatment. I'm sure I'll still have to go to the doctor, I'm just hesitant to do it. I'm not really a fan of goin to the doctors! Thanks for any and all help.
