Almost always horny but shy to act on it

Me and my fiance do "it" 1 to 2 times a week. He is almost 30, I'm 24...

I did tell him I would like it more, but I don't really try to initiate sex when I'm horny and he's busy watching tv or something... I feel like I don't want to make him feel like I just want sex.

But I find myself waking up horny the morning after... while he's sleeping... Should I tell him I'm horny almost all the time?... What should I do?... ADVICE PLEASE
