Pimple on my penis or herpes/genital wart?

About 2, 2 and a half weeks ago, i noticed 2 bumps on my penis, the day after i shaved my pubic region, that started to look like pimples. They began to hurt so i popped the one and white pus came out, like a pimple. That bump has since decreased in size and is almost gone. A few days ago, i popped the other bump and white pus came out of that one as well, however, there is became a small open wound due to the force i used to pop it, which is now scarring over. Also, 2 very tiny little bumps are starting to develop on a different part of my penis. Sort of like the starting of pimples too. But i'm scared because i'm not positive if they are/were pimples and i wondered if they could be an STD? The last time i had any form of sex was in the beginning of August and yes, it was unprotected. Are these things just pimples or should i get checked out to see if they're genital warts?

dude, the same thing happens to me sometimes, and at first i was really scared cos i did have unprotected sex with a girl that makes me think that i realllllly should have wrapped up, however i did some reasearch and from what ive read.... herpes tend to form up in tight clusters, almost always break out in the exact same places every time, and they get a nasty looking crusty yellow film that developes over them after they hav been popped. while a pimple can pop up anywhere that theres porus skin, and they just heals over like a scab after you pop them...

i hope this helps mayne, and that it turns out to just be zits like it did in my case lol :)
