hard lumps on penis ??

I had unprotected sex about a month ago and now i have a 2 very hard lumps under the skin and on the under side of my penis.  They popped up over night and have not seem to do anything this last week.   They only bother me because i keep checking them, and i dont have any other symptoms.  Everything else is completely normal.
what could this be ??
thanks.

Hi.

We can't tell you what this could be because we don't have a better description. You MUST go to your URO and talk to him. Don't worry, it might not be that serious BUT pay your doc a visit. See you.

You might have some infected hair follicles.  Hard lumps under the skin aren't likely to be stds, but get it checked.
