Guy insisted for sexual favors on first date is it a red flag?

So I went out with a guy I met last night and he was very nice and very respectful and cute we decided to hangout nearby his house and I told him I’m on my period so I don’t wanna do anything sexual I’m not on my period I just said that cuz I don’t wanna do nothing like that yet but we cuddled and he obviously got excited biting his lip etc and we start making out and he goes we don’t have to have sex but can we do other stuff like a bj I told him let’s wait for next time like twice he said never mind but he insisted on that and said we can do other stuff next time etc and he was a gentleman after and was actually nice and said he likes me but I just wanna kno is this a red flag or do guys normally act like that on the first date cuz I’ve already had 3 or 4 guys act like this it always turns a bit sexual weather I like it or not should I block him or see where things go and give him a chance
