Why do some men become a different person during sex?

[Anonymous]

I know a guy that was overly sensitive, very respectful and all in all just a huge simp for me. When we talk he seems interested but always afraid to touch me and very timid. However when we do have sex he is very forceful, dominant and inconsiderate (for instance he would fuck my face and cum in my mouth without warning me, pin me down and aggressively stick his tongue in my mouth and keep kissing me no matter how much I turn my face away etc etc). I can’t recognize him during sex at all. Is this normal?

Nothing will boost your confidence like a woman who wants to have sex with YOU
