Would this turn you off?

Whenever I’m on my period I don’t want to have sex I’m not into it, not my thing. My fwb legit straight goes I should go over as it would be nice if I’d give him a blow job “because it’s sometimes nice to treat your partner” he then proceeds to say “being selfless is a good trait to have”. That really pissed me off because he always finishes and when I don’t and he knows he does nothing unless I tell him. So I said to him “when have you never not be treated” and he goes “sometimes it’s nice to do something else for someone and not expect anything in return”. Like sorry? I don’t know I’m turned off with what he said would you be? The fact he can’t wait till I’m off my period and NEEDS a blowjob.
