Hey there! Thanks for posting.

Just as it's really important for us to listen to our bodies to give us clues about our emotions, it can be just as important for us to listen to our emotions regarding our bodies. I am glad it doesn't seem to be affecting your daily life, or distracting you from things you should otherwise be doing, but (and please correct me if I'm wrong here) it sounds like by "compulsive" you might mean "use as a coping tool to distract from unwanted emotions." Is that correct? If so, then it might explain why something feels off to you.

Masturbation in and of itself is a completely natural, healthy thing to do. But, like anything, it can be done for the wrong reasons, and that can make it an unwise choice if you frequently use it to cope with difficult emotions. Eventually the unconscious associations might begin to affect your feelings about your body and your relationship with it. And that's something to definitely be aware of.

I would absolutely talk to your therapist about this. It sounds like a good idea, and they know you best and might have a more specific idea about how to help you. As for it affecting your period, it could possibly be, but that would most likely be something to discuss with your PCP. Stress is also a very common reason for affecting the menstrual cycle, and that could also be at play here. If talking with your PCP right now sounds too uncomfortable, I would suggest at least talking to your therapist and what they have to say.
