<human>: So here's the story. I'm a guy, and pretty darn straight. Someone I met and haven't seen since 7 years ago is coming to visit me for a few days. He's actually going quite out of his way to come visit me, which makes me a little suspicious if he is secretly hopeful that we might get down together. 

He is definitely gay and I'm pretty sure is at least a little attracted to me. 

I don't want a situation with sexual tension or one that is a letdown for him. I want to make it clear that we are seeing each other purely as friends, but I don't want to sound accusatory, especially if he *weren't* pining after me after all. I don't know how to do this tactfully and gently without making me seem homophobic or hurting him in any way. He's a cool dude.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Friend is traveling long distance to see me, I want to make sure, in a nice way, that he isn't hoping to get romantic with me.
