Sex does interest me

I’ve tried talking to my boyfriend about it suggesting new things like chocking me or pulling my hair stuff of that nature we he says we can but never ends up doing anything that I suggested which isn’t a problem I can understand he may not feel comfortable. But the sex is so boring I’m never satisfied at the end🙍🏼‍♀️sometimes he ends up cummin fast then falls asleep which is annoying as well kind of feels like he doesn’t want to please me but please himself. I really like him I know sex isn’t like a need but it’s like I rather touch myself or have him touch or go down on me while I’ll think about him being in me but soon as he’s in me I don’t feel pressured. It’s pretty big down there so it’s just like why am I not enjoying what he’s giving even without him doing the things I suggested. Any suggestions?
