“What are we”

So I have been seeing this guy for 5 months. YES 5 months and he hasn’t asked me to be his gf yet. We just started to have sex and it’s great. He tells me every time I talk about what are we he says just wait and don’t worry.. he says he’s not in this for the sex and he really likes me and I even met the parents.. but we’re not “together” what should I do?! I’m tired of waiting but don’t want to push him away by keep on asking what are we
