Took much sex!

So when it comes to sex my SO just can’t get enough and Of course there’s a limit to everything and I much rather him want me than not want me but after having sex he wants to do it again then again until im sore af and can’t say no because I feel bad and then hours later he’ll want to do it even more. Is this healthy? Sometimes I wanna say no but give in or when I do say no he gives me attitude but denies it if I ask and he’ll be like I’m ok .. but I know he’s not if I don’t give it to him
