Need a lot of help here.

I'll start by saying that I'm 21, and my mom has been trying to set me up with a guy, who is 36, she had met that works on a cruise ship in Australia, and is from Canada. I've never been in a ~real~ relationship, a couple of dates and I made out with a stranger in a club once, and that's the extent of my experience... what I'm trying to say is I'm a virgin, lol. The guy that my mom is setting me up with is 36, and has previously been engaged in the past but is not married and doesn't have any kids.

We've had a few phone calls, and while I feel awkward when he describes something that I say as sexy and that it's "a real turn-on" for him, he's been hinting at phone sex the last call, and I felt completely uncomfortable. I voiced how I felt and from there the conversation got really awkward. He didn't call me for a couple of days, and he called me earlier but I had missed it.

I have no idea where to go with this relationship, he's a very nice guy and I like talking to him, but not when he keeps telling me how much I turn him on. I feel like we're looking for two different kinds of relationships, he's looking for something more mature that I'm just not ready for yet. Plus, I would much rather connect on an emotional level, which he seems to have glossed over.

I feel like I answered my question just getting all my thoughts down in one place, but what I really need most is a way to explain to him that I'm not interested, or to make sure I have my assumptions right.

Thank you so much!
