Thoughts ??

So Ive been dating this guy. He has a past of sleeping around and has even been open to me about it. He’s cut off all these other females for me. We flirt with each other a lot. Intense make out sessions, he tells me all the sexual things he wants to do with me but we still haven’t had sex. Sometimes I bring it up and ask when we are gonna and he says “idk” and hugs me . Does this mean he doesn’t want to? Or just waiting for the right time?
