Am I bi-sexual?

Since I first shoved something in my butt at about ***********, I've had many fantasies and fetishes. Usually it involved a beautiful female ass...or my own, guess you can say I'm at least a butt man. About 18 years ago I met what would become my third wife. We were both in our late 30's, she was my first redhead so yeah, she was a freak! After about 3 months she asked if I had any fantasies, I said yes, but you tell me yours first. So she grabbed a pen and paper and started writing. About ten minutes later she handed it to me, as I read the note she had written in detail about how she always wanted to fuck a man in the ass! I was almost in shock, I had found "the one"! We couldn't get to the toy store fast enough! When we made it back home it was straight to the shower, I went first then she followed sayin "you better be ready for my cock when I come in there" I laid there for what seemed like an hour wondering if I had made the right decision because my cock wasn't responding to my thoughts. Soon after the light went out in the bathroom and she walked into the bedroom wearing the 8 inch strap-on that her and the 20 something girl at the store decided on. That was the most beautiful thing I had ever seen to that point in my life, a sexy woman wearing a strap-on! From the foot of the bed she started at my ankle and ran her tongue to the tip of my no hard cock, raised my legs in the air and went balls deep on the first stroke with her already lubed cock! The whole experience only lasted about 45 seconds because she came almost immediately which I knew from her juices gushing down my crack, yes she was a squirter too! But that was my first ever hands free orgasm! After that amazing night we had many others that went all the way to her actually fisting me! God I will remember those days forever Donna, thank you lover! Sorry to say we parted ways but what an amazing time we had together! Since then I've had a couple of girlfriends that have fisted me or strap-on fucked me, but never anything as passion fill as Donna and I had together! These days my taste has evolved with all the cute trans people out here! Always thought about sucking my own cock but never shared that thought with anyone. A nicely shaved circumcised shemale about 5 to 6 inches would be perfect because I will never be able to reach my own unfortunately. My new fantasy would be for a girl to pretend we were going to do a spit-roast on me, 2 girls with strap-ons! I would be blindfolded on my back, head hanging over the bed when they come in. One would take my ass, the other being, unknown to me, non female would face fuck me and cum in my mouth!
I would love to do this, but it will probably always remain a fantasy unfortunately. So what do you think? Am I just a man with fantasies or am I bi-sexual?
