I personally believe that the femdom problem come from low self steem. Leaving the sexism aside, people want it or not, the man is expected to me dominant in a intercourse in the majority of cases. Then, what happens is that nowadays a lot of men think that they can't perform well in that role due to a lot of reasons: low self steem, overweight, small penis (this is often not the reality, but we end up thinking about that because of porn),
premature ejaculation, etc... This lead to the rise of the dominant female.
I don't think that females being dominant is a bad thing, in fact, some sexual positions create that exact situation, and it's all good, but when it leads to masochism it turns into something bad.
NoFap might help you with that, if it's related to porn consumption, but I still think that there's more than just the porn addiction into that situation.
