Ask him to be my lover?

So I met this young guy a few weeks back and I am going through a divorce. I really just want a lover. We did connect two weeks ago and we have sent each other sexy chats.

This week I have asked him if we could go out for a drink but he seems busy. Do I just come strait out and say I want sex tonight? Help!!!! I haven’t every don’t this before and I am 12 years older than he is.
