Is it normal that i don’t like having casual sex in my home/bed?

I don’t mind the occasional hook up or one night stand, I’ll do it at his place, a hotel, even my car, but casual sex I don’t want in my bed. I’m not OCD, but am quirky about my bed, I shower at night after exercising or getting dirty, but not every night.I like it clean. I only started dating again after a long absence (I gave up, didn’t care, just focussed on works, family and friends) but now I want a partner) , so this will be my first experience in my own home, before I lived with my parents so didn’t do it there. My last real relationship of 1.5 years, he lived alone so we went there. I tell hookups I have a roommate, but they think I’m lying and have a husband (ha I wish). Some people say hookups lead to relationships, so I’m not sure if lying is the best. But then my hookups live with their parents or roommates so they could be lying. If I was in an exclusive relationship and loved the guy I would have sex in my bed, but a casual one night or ongoing just sex, no way. I’m 38 and female.
