Sex tips for a lazy girl

I am a pillow princess, I usually don’t do much because I don’t have to but sometimes I feel ‘useless’, any tips on what to do for my partner (M)? I can’t ride for long my legs hurt, first world problem I know 🤣 but because I can’t do it for long I feel like I let him down, I also don’t really like anything from behind, reverse cowgirl, doggy etc it’s just too much for too long and becomes painful. Any tips on what I can do so he’s not always doing the work, I don’t mind doing the things I mentioned but I can’t go it for long and I’m sure it’s annoying for him when he’s getting close but I can’t keep going.
