Am i wrong ?

I just separated about two months ago and my ex text me after a week saying that he wanted to work things out, so i agreed because he wanted to go to couples counseling, we tried it but kept on putting excuses to go, and i was hurt because i ended up breaking up with him. Ever since he never spoke to me till yesterday, he wanted to get some stuff he left here, and i lied to him saying i wasnt gonna be here all week. Long story short, i smoked lastnight and as i was on snapchat he sent me a message saying he wanted to have sex, and i was acting hard to get 🤣 i was too faded and i knocked out, and this morning i left him on seen and he text me back saying he wanted sex no lie and lowkey i had been wanting to text him only for sex but i didnt want to get denied lol so he just left right now and we agreed to be sex buddies so my question is am i wrong for asking him that i was okay with only calling him when i want sex ?
