This sounds like "molluscum contagiosum". Go to a Derma and he/she will burn them off. They will spread if untreated, but the body will clear them after a while if you do nothing. They are contagious, but once gone, are gone forever. I had this, no big deal, just get them diagnosed and removed ASAP.
ps. It is no big deal
Hard to say, but surely not genital warts. If you are convinced it is a sort of std, perhaps molluscum contagiosum? Although truth be told it could simply be from some kind of irritation and/or friction.
