21 turning 22 and I have an unusual bald pattern

[Pentagon101]

So I lost my hair density when high school ended. I blaim genes or masturbation etc.
Since most of you guys here have more knowledge about hair and hair loss. Would you care to answer my questions

Does masturbation cause hair loss ?

If your mom had some bad balding spots, does that mean the male child will suffer the same ?

Does smoking causes baldness ?
