Well, posts on this topic have slowed down!
I've been busy focusing on another topic on PF concerning desires with my wife. You may have read some of it. This topic is kind of related to that one. But, some further thoughts on this one!
I've had some degree of same sex attraction since "experimenting" with my best friend during sleepovers and long periods of unsupervised "play time" when we were probably in elementary/middle school (ages maybe 11-13). I still think back on those days and it gets me aroused. I didn't think of it as sex. I just thought of it as playing naked with each other with little, but very hard and sensitive, penises. My prepubescent hormones were raging and I loved it.
I've been with my wife for 50 years now and we've had lots of great sex but I still have that Bi-Curiosity. When I say same sex attraction, it's really been same genitalia attraction. I've never been attracted to "men" per se. Just their fun parts.
I think it's interesting that this topic is specifically "Over 50...." I've noticed, now that I'm much older, that I'm starting to be attracted to the idea of actually having a man make love to me and not just let me play with his naughty parts.
I think there may be hormones involved in this change in attraction. (The fact that my wife is no longer interested in sex, or more specifically, mostly interested in NOT having sex, may be a contributing factor. Her hormones may be at play there as well.) I haven't been tested but I think my testosterone is way off and my estrogen in on the rise. I've developed a couple of cute, relatively little compared to my wife's, but distinct "man boobs". My wife has confirmed that I've definitely got tits! I actually really like them. Her not so much. My nipples are quite sensitive and when lightly touched (or played with) it goes straight to my genitals. It gets my prostate in gear making semen (not an entirely unpleasant sensation)!
I'm not Trans but my body seems to be making some transitions on it's own. I believe I have what has been referred to as Autogynephilia. When I look at myself naked in the full length mirror I see myself as a woman and I LIKE it!

I imagine a strong virile man taking me in his arms and treating me like a woman should be treated in bed. Of course, I have NO actual desire to become a woman. I am who I am and, though it causes me lots of frustration and mental health problems, I accept it. I kinda love it actually but, at the same time, it's really not good.
So, anyway this is about my observations on the hormonal affect on sexual attraction but I've enjoyed baring my soul and doing a psychological striptease (Yes, I have a predilection for exposing myself to consenting adults

I also am inclined to be submissive but that's probably a whole other topic!

)
That's all for now. Talk amongst yourselves and have a nice day!
