Parents and sleep overs

I'm 20 and my boyfriend is 21. We're about to be dating for a year and my boyfriend is getting his own apartment soon. So I really want to tell my parents that I want to sleep over his place sometimes but I have no idea how to successfully convince them of it. Any ideas? Btw (this may seem like unnecessary info but isn't lol) my parents are Hispanic and somewhat strict not really. And my mom is super religious but pretty open minded. If you're Latina then you know that shit doesn't fly in your house.
