My bf won’t let me see him cum /u/slipknotstan666

So I’ve had sex with my bf 5 times now and I’ve known him for about a year he’s great in bed however the only thing that ruins it is the fact that he pulls out before he cums because he doesn’t want to finish inside me which is fine but he always finishes before I do he quickly pulls out and runs to finish in the bathroom closing the door and often leaving me just laying there. We then cuddle until he recovers and repeat the same process a couple more times. I don’t mind if he doesn’t cum inside me but it would be a huge turn on to see him cum anywhere on me. Why does he do this and how do I tell him I wanna see him cum? Btw we don’t use condoms but I’m on bc
