It is an unusual guy who would not want sex with someone they feel emotional about. Doesn't mean that is all they are after. After all, assume that and you never get into a relationship. One has to take a chance, come out of one's comfort zone, and live a little. But you go at a pace you can cope with.
Difficult though that can be, it's far easier than having to be the one who admits to feelings first. That's a much larger risk of getting hurt, especially if, like I was, one is daft (aka shy) enough to not move early on but spend ages trying to find the bottle to say something.
You might let him know that he seems to be laying the "you're beautiful" thing on a bit thick, unless you like that of course.
As folk have said, let it progress at your own pace. Either it'll last, or it'll end and you can be happy for the time it was there and you enjoyed the companionship.
