I posted this recently on a male/female session, in response to a specific question. That question will be obvious as the story moves along.
I'll call her the Goddess. We met around 2002 when I found the old wb270.com site and began seeing female bodybuilders. I was a regular of hers until one of her last U.S. trips in 2009. She was a bodybuilder back then and a full dominatrix and is one of the most gorgeous and strong Amazons I have ever met. She's from central Europe, jet black hair, my height (around 6 ft. 1 in.) and she listed herself as something like 44DDD-26-36. Plus her muscles were then, probably still are, impressive.
We always did a form of "You Amazon Queen, Me captured Tarzan," role play, which involved quasi-non competitive wrestling. (I say "quasi" because at times "Tarzan" might briefly get the upper hand... very briefly.) She is imaginative and creative, with a great sense of humor and costuming. I probably saw her once a year or so, and we developed a great chemistry, exchanging an occasional email or phone call. I didn't see her for a year and a half at one point, and in that time I lost weight and was working out regularly. I made the appointment when she was in town and didn't tell her about my training. It was summer and I went there in shorts, golf shirt and sandals. She opened the door, was in shock, and threw me against the wall and pinning me there, asking questions and ordering me to strip. We began wrestling and it was getting more and more sensual. She pinned me against the wall and suddenly slid down and pleasured me for four or five seconds, which was astounding given her strict demeanor. She looked up and smiled, saying, "Do you want me to use a strap on?" I politely said no, she was fine with that, and I was then allowed to pleasure myself while she posed and talked trash to me.
After that, as only a dumb, horny middle aged guy can be (Diana was in her mid 30s and I was around 50) that we might get at least slightly intimate during our next session. Wrong. Diana used my lust against me mentally and physically when I wanted to orally pleasure her, resisting and reminding me that she was the Mistress and I was just her "jungle pet." As I left that session and got into my car I couldn't figure out how I could have been so wrong?
Finally it hit me. I immediately called her, thanking her for another wonderful session but I had to find out what her story was. I came up with something diplomatic like, "You're so gorgeous and strong... really unique. You are a perfect combo of female sex appeal and male muscular power." She was silent for several seconds. I thought I was in trouble. She finally laughed, saying, "You're the only sub who ever guessed." I thought she meant being a trans woman. But as I learned later, and she revealed via interviews in her own country, she was born intersex. That means people who do not fit typical binary notions of male or female bodies. By all outward appearances she was all woman. Upon hearing the news this middle aged straight guy was not horrified that I was horny over someone like Diana.
I saw her a two more times after that revelation and she became more intimate with me, but I was still her sub. If she was still coming to the U.S. for sessions I'd probably see her again. Have I ever sought out a trans woman or intersex person since? The Goddess that I served was, in my eyes and my feelings, all woman. It taught me a lot about myself and sexuality in general.
