Can anyone explain to me in biological way if no fap or fap is better if I'm trying to go into a difficult stem area and want to be top of my class?

Pros of no fap: more time, more motivation, more energy. I also am losing my hair and I noticed that after fapping the next shower these is considerably more hair falling out.

Cons of no fap: can't stop thinking about sex. In class, all I can think about it wanting to talk to the beautiful girls and having a relationship with them. This can be fixed by finding a beautiful girl and making sex with her but then we come back to the fact that whenever I was in a relationship all of my needs were satisfied and therefore I couldn't muster up the self discipline to study/ do my assignments

I really don't know what to do bros. All I want in life is to be healthy and make valuable contributions to the science community.
