It sounds as though these may be molluscum warts. These are not caused by the same virus which causes ordinary genital warts. They are common, occur in children and adults, and despite their full name (molluscum contagiosum) hardly ever are present in family and sexual contacts. They are listed as a possible STD, but that is rare, in my experience. They can treated with acids or liquid nitrogen, or you can just wait them to go away, which usually takes several months.
Of course, you need a proper diagnosis, so you should get them looked at to be sure.
Take care.
