Drunk Late Night Hookup Mistakes Me For A Girl

In my teens i used to practice makeup a lot and got quite good and used to chat to guys on a few sites with the occasional meet.
A very attractive man messaged me one evening on a swingers site and we ended up meeting in a hotel by me so I got there earlier than him to do my outfit and make-up and stuff. I can always get quite fem but every now and then I get it perfect lol.
Told me when he arrives he wants me on my knees with my mouth open so thats what I did and gave him a proper long and deep blowjob until he cum. He sat on the bed then while i carried on sucking his dick for a good hour or 2 lol. Nodded when he asked to fuck me, puts his condom on, runs his fingers down as if i have a virgina and pulls his hand away and says "how the hell are you a guy?". (Bear in mind my username was also something like BiSissySlut).
He was okay with it though. Ended up with his dick in my ass lol.
Still speak to him now and then and im still the only guy hes had his cock in lol. The mad part is i made him cum like 6 times that night so he definitely enjoyed it
