MY CHILDS FATHER

So my childs dad wants to come over today Were pretty cool we take care of our son but yesterday he let out some feelings I didn't know he still had.. we so happened to mention our sex lives he knows I haven't had sex since I was like 2 months pregnant so now it's been a whole year. He says he wanna come and end my "dry spell' lol should I let him come over and we have sex or would it be like he's just coming to use me or something I really don't even know if I'm ready or not.
