I wonder if porn in adolescence have any correlation with being short. Does porn affect growth hormone level? Are there any research in this field?
I don't think it has effect. Most people are short because both/either of their parents are short- it's genetic. I'm tall because my Dad is tall. I fapped a lot in my adolescence and I'm over 6ft. A lot of dogmatic info about MO's side effects out there. Another popular one being that MOing causes pimples- absolute BS.
I don't think there is a correlation. Unless if the person is hunched over a lot and their back grew that way maybe.
