How long does molluscum keep spreading?

Hello. I’m 27M and I got molluscum contagiosum on my genitals and groin about 7 weeks ago — I got it from a one-night stand (needless to say, I haven’t had any contact with her since).

Since then, new bumps have been appearing occasionally. Two weeks ago I had some of them treated with cryotherapy, and I have another session scheduled in a month because new ones showed up again last week.

How long should I expect new molluscum bumps to keep appearing?
