Bumps

Has anyone ever gotten a single flat, slightly raised bump on the inside of their butt cheek? Quick backstory: I was diagnosed with HSV2 five months ago and I take a daily suppressant. The bump I described was not painful, itchy, or inflamed. I only noticed it because I do self-inspections a couple of times a week. Does that happen to anyone else? Is it a flare up? I only ask because I had sex with my boyfriend and he is well aware that I have HSV. But I want to ensure I don’t transfer it to him. We use protection and of course the medication I mentioned. Yes I know, when with medication it’s not 100% non-transferable but I would be upset if I gave it to him.
