Don't pop them and pulling out is not going to prevent STD's or pregancy.
Bumps can be so many different things, most of the time non-STD related. Best advice is to see a Dr for proper diagnosis.
yes with 2 people one being my boyfriend who I have been active with for months now. They both pulled out if that makes a difference. The bumps went down in size when popped and don't really hurt except right after I pop them for a minute or so.
Have you had any unprotected sexual encounters? It does sound more like an ingrown hair than anything though.
