Bisexual man who's only been with men... not sure what to think of thoughts I'm having... long post please need advice [18yo] [NSFW]

So I'm an 18yo closeted bi man attending college. I'm closeted just because I want to be, and don't feel the need to let anyone know about my sex life. For a long while, I avoided any seeking any sexual partners throughout my teen years, as I didn't want to accept it back then. So I pretty much had only kissed girls and got a few odd blowjobs and handjobs. As I got to college the urge for men grew stronger, and I began meeting up with random guys on Craigslist, all of them much older than me. I had one night stands with 4 different men. The first 3 were just making out, mutual oral and handjobs. The last one I fucked in the ass, and I loved it, being my first penetrative sex of any kind. And then there was the 5th. Oh boy. But first to give a little more background:As I realized I was bi, since my young teen years, I realized the men I would be attracted to were much older than me. I just loved the idea of submitting to the will of an older man, sucking him off, and letting him fuck me. As I watched more gay porn and did more research, I realized I was into what are called "daddys." I have never been attracted to my own father, and I've always had a fine relationship with him so I don't feel I have "daddy issues", but I always enjoyed thinking about calling the older gay men in my fantasies, and roleplaying as their son.Back to the 5th guy. I met him off Craigslist as well. He's a gorgeous 45yo Asian man with a beautiful cock. So I went to his place one night and everything was so great I let him take my anal virginity. It was so hot. Anyway, I'm going back tonight and we decided for the sake of anonymity we'd be roleplaying father and son. The idea of being dominated by daddy and being his little slut turns me on so much, and part of me is so horny and excited to finally roleplay this fantasy that I've had for as long as I can remember. But I am also apprehensive. It feels so wrong but I think that's why I like it. Anyone I guess I'm looking for anyone else who's maybe acted out this type of fantasy before just so I feel a little bit normal and I want to know if this is wrong.TL;DR: I'm 18yo meeting up with a 45yo man to act out daddy son fantasies, is there something wrong with me?
