All of this is true. In the early 2000s I had sessions in the US with a European FBB who was very theatrical and a dominatrix. We were around the same height, 6 feet or so, she was around 180 or 190 lbs., I was a 20 or 25 lbs. heavier. She was a tall, busty brunette. I'd see her once a year for four years, and every time I saw her the sessions got more intense... scissors, mostly non-competitive wrestling, body worship... wonderful. The fourth visit I had been on a fitness program and gained some muscle for a middle-aged guy. (She was around 30, 32.) When she saw me as I walked into her hotel room she was pleasantly shocked. She was all over me and I was all over her, wrestling foreplay I guess you'd call it. She had me against the wall and slid down to her knees, grabbed my manhood and began to pleasure me for 20, 30 seconds. She then looked up, smiling and asked, "You want a strap-on?" I was never a fan and said no. We continued the session, I was ordered to pleasure myself, and left with a smile on my face.
Several months later she came back to the US. We exchanged emails and spoke once on the phone. I "knew" I was going to be her "stud" during the sessions. All the indications were there. I arrived, she was as sexy as hell, and we did our wrestling foreplay again. I wanted to warm her up by orally pleasing her. She used all of her strength to stop me. I backed off. It was a great session, but not what I had planned.
Going home I thought, "I couldn't be that wrong" and kinda figured it out. I called her to thank her for the session and finally said to her something like, "I thought we were going to do more... but I realized you are very special." There was silence on the phone for a long three or four seconds and she laughed, "You figured it out!" She was transsexual with, what we joked, was a "girl cock." I didn't feel completely deceived, I didn't feel a lot of things a straight man should feel. I got to know her and was turned on. She looked like the best Amazon I ever served. I was still turned on but she retired. I still wonder if I had said yes that "strap on" would have been one... or her.
