I’m addicted to my boyfriend. I want to be having sex with him all the time but I try to keep cool since we’ve only just started dating and we’re trying to take things slower. How can I control this?

I’m 23F with 32M. We’ve been dating for a little awhile but wanted something serious so we have been taking things slower. He hasn’t had sex in years. Every time we have sex he’s cumming in no time like before he even puts it in me. I’m always telling him he’s sexy and hot and I do feel like it’s overwhelming to him since he’s never been in a relationship nor has he had a lot of attention I don’t think. How can I control my hormones so I’m not trying to fuck all the time? I’m not like this with everyone I just really like him and think he’s so attractive
