Heard through the vine that my ex is coming to my new town soon. I live very far away.

We'd broken up before I left and stayed in touch, but after coming here I decided I need to stop communicating with her. This was mostly because I didn't want to lead her along like I still cared in that way. That's just how I feel about relationships.

The thought of her coming here only incites sexual excitement for me. She and I had awesome sexual chemistry and it's still the best I've had yet, though I've seen a few other people since.

How do I let her know that sex is basically all I'd want if she came here? I'd be ok with small talk and small catching up after, but in no way do I want to re-hatch feelings or start getting "how are you" texts afterwords.

Do I just need to man up and tell her I only want the casual sex? Or does this need to stay buried no matter how tempting the sex is? I'm not worried about relapsing my feelings at all, but I don't want some big mess from her if I can avoid it.
