how to change a casual relationship to sex-only

i have been dating this guy for 8 months. i have pretty strong feeling for him but to him it is just a good friendship with very good sex. we go to dinner and the movies and have sex. i think he is seeing other women. i want to change it to sex only -- he just stops by for sex. we are both in our mid fifties. please help me think of ideas so i don't have to confront this. i can't stand up to him too well. thanks

Why do you want to change it? He's no good at going to dinner and the movies?

i would take all the free stuff!! haha

i would just say one night, when he asks you out, fancy skipping dinner and coming round for kinky time? then just make a habit of it.

you never know, he might appreciate you saving his monies! :D
