I've only had 1 sexual partner, but I haven't actually had sex with her just oral. The last time I had oral was the night before I discovered the red bump there's only 1 it looks like a pimple I already looked up pics of syphilis, genital warts, and herpes. It looks nothing like any of these. I noticed it as I was getting in the shower the next day. I can pop it first a fluid like when a pimple is popped comes out then blood its at the base of my penis. It just looks like a pimple, please help?

Don't mean to sound... condescending, but its probably... a pimple. You can get them anywhere you know. Nothing to worry about by the sounds of it. If it don't clear up within a week. Man up and see your doctor. And oral is sex silly. You can get herpes from oral. Don't let her give you a blow job if she has a cold sore. It could infect your penis and give you herpes. And herpes never goes away... EVER.

Both of you, even a pimple on a penis cant be cause for alarm. And, Anonemy stop trying to 'pop' it, that will do it no good at all, and could give you an infection.

And yes, chazit, you can get a pimple anywhere, but the OP is just that an OP and to give advice the way you have is not a good idea. You can't be general unless you have some complete medical knowledge of what you are talking about.

Edit: sorry, meant to say CAN BE CAUSE FOR ALARM

You do know there are many more germs in the mouth than anywhere else often. And oral can give you many STD also, and many infections. I will assume you did not use protection?

It could be anything from a sore from friction, to an infection to just a pimple.

Only a medical check up will show for sure.
One thing about being sexually active, you have to be able and willing to be checked medically.
