HowCome?

OK, I'm eighteen and a cute bisexual guy that's probably more gay than bi. I don't understand why all the stereotypes? Because I like getting fuck'd in a relationship with another guy and I love suck'n too, but underneath another boy or man is kinda special to me. They all want to fuck me because of my beautiful ass that they fantasize about while I'm suck'n them. I love it when they do, cum squirting inside of me is the best thing and I don't let anyone fuck me, I'm kinda a little promiscuous but boyslut like, I really don't like bigger cocks, normal is just fine thank you. What bothers me is that after being with a new man friend he was a bit larger and after he was done he said " Okay, nice ass! You can put your cute little boy panties back on, you've finally been with a real man and you're my boy bitch now!"
First of all I'm not his "Boy bitch" and even though I'm kinda fem looking for an 18 year old boy I'm a pretty athlete too. He's not the only one who said that before. How come if a man or boy cums in my ass I'm his bitch? I think they're my bitch because I made them cum in my ass!
