Single bump randomly appears on thighs

[kycat1]

Any opinions on what this bump might be? For about 2 years, I’ve noticed one popping up randomly. It’s only ever one, never a cluster. They are always small, the size of a pencil point and have a black dot in the center. They are slightly itchy, not unbearably itchy at all, just slightly. Never painful. I haven’t noticed any sort of pus or anything. They are basically always on my thigh, specifically upper thigh. Maybe as far in as my bikini line, but I’ve never noticed them in my actual genital area. Eventually the bump will go away and I’ll get another one. I don’t get them in bursts, I kind of just always have one - one comes and goes and another comes. Sometimes they leave a little discolored spot in it’s place. I’ve been in a monogamous relationship for almost 10 years and have no reason to suspect any infidelity. My partner does not have them. The closest thing I can find is molluscum contagiosum, but still interesting that my partner doesn’t have them (and we’ve definitely had intercourse while one has been present in my thigh area).

Is there a way to attach an image?
