SHOULD I?????!????!

Da
Okay so tell me this, is it okay to just want sex from a guy. Even though he is a complete waste of time in terms of a relationship, I went over to his house today and so many red flags in term of his hospitality. But I still want sex and I just feel stupid for still wanting it cause I know he's gonna treat me like shit.
Oh FYI he didn't even ask if reached home safely...
