NEED ADVICE: What is going on?

So about a week ago after having sex I noticed little bumps near the opening of my vagina and partially on my anus. They aren’t sores just little bumps. When I bust them however they bleed. They do not hurt whatsoever. Now a little more information on the person I have sex with: we have been having sex for the past few months and I have been tested for STDs these past few months as well (like to be safe). So I figured it wasn’t an STD or STI because it would’ve showed up sooner. Any idea what it may be?
