Sex drive 😐

I can't help but say, I love sex I could do it everyday if my S.O. would be willing lol. Anyways, the sex is always fantastic, and it lasts maybe 30 minutes on a good day. But he doesn't go long, and when he's done, he's done. It's rollover and go to sleep or get off and cuddle. I just want to cum too, how can I approach this with him?
