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.
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
