Sex with SO

My sex drive is usually at a 10 no matter what mood I'm in. My bfs sex drive is pretty high too. And we have sex just about everyday, if not 2/3 times a day. But idk if I wear him out sometimes or not, or if he wants more. I ALWAYS want more. But would it be pushy to ask for more sex than we already have? And we are ttc, fyi.
