Guy Friend Wants To Have Sex With Me

My Friend is joining the military and he leaves in a couple days. He's been trying to get laid all day but none of the girls he talks to wants to sleep with him. So he asked me. 😐 I've liked him before, I'm not sure if that's a good idea. I never really answered his question when he asked me if I wanted to. I stalled and changed the subject. I felt weird about it and I kind of wanted to slap him. 😅😂 He thinks our friendship isn't going to change because he's leaving anyway, and it's not weird, and that it shouldn't be cause we're friends.
Mind you now, he Said all of this while he Was drinking. And when he drinks, he speaks the truth.. so. I'm afraid. I'm just hoping he forgets that he asked me that question.
