Run of the mill confusion?

...Hormones? a phase? it's natural? well...you be the judge i guess.

By the way, i will use the term "shemale" here, which i know is a bit offensive to some people, however, i am using it deliberately because i am referring to transsexual women that are probably marketed to men in the porn industry.

I am a 17 year old heterosexual male,and recently my sexual fantasys (which where your typical me screwing some hot babe i created in my mind) have...expanded.. to include a little bit of sexual submission.
In these fantasys i imagine myself basically getting pegged by crowed of woman...or...(here's the catch) shemales....

I thought about substituting either of these fantasy partners with an actual guy and i lost my boner or at least the spark sort of died...See the male physical form doesn't attract me in the slightest...what attracts me is the female form and that submission element that can only be achieved by me getting ****ed by a **** (for me at least).

The shemale kinda fits in perfectly here...it gives me the female form which i enjoy...and the submission.
After i orgasm...the fantasy ends...and i am back to my normal self...where the thought of having sex with an actual shemale kinda makes me uncomfortable.

Also, this fantasy is sort of cycled... i get the need to jerk off to a fantasy similar to this every few weeks...then it just resides in the recesses of my mind.

So, slightly gay? bi-curious... or just a guy with a freak flag that should be left to fly freely.
The whole fantasy is me probably trying to keep things sexually interesting, but this just for my peace of mind.

Sexuality is a very unique thing and I really wouldn't worry too much about trying to classify where you fit. It really seems that your fantasy is, as you said, about being submissive and that is one individual that could lead to that submission. A lot of people have different fantasies, both straight and gay. I really wouldn't worry - as long as it isn't hurting you or others it doesn't matter.

I see you're new, so welcome to PC.
It's true; our sexuality is complicated. All kinds of stuff turns me on that I have never admitted out loud because I know it would disturb people, and lots of stuff confuses me about my sexuality as well, when I think about it. The way I've heard it explained is, we get so caught up in the 'right' and 'wrong' of it and forget that they are just harmless thoughts/fantasies. If you're wondering if that has anything to do with your sexuality, or wonder why you are being turned on by one type of person with a penis when you have no sexual interest in men, of course you can wonder but the bottom line is, if you find it sexy, if it's not hurting anyone, then you're fine. We get so hung up on sexuality all the time that we forget it is a normal part of our chemistry. What turns us on turns us on. It's really difficult to help that.

Would a girl with a strap-on do it for you as well. That may be easier to find, but I don't know...I know I'd be interested in acting as the "shemale" or as a male (I'm biologically female, by the way) when I'm with a biological male.

I may be in the minority though...

"Pegging" is becoming more and more common these days. Heck, there's a radio show here where they have to keep sending a woman they know "referrals" because guys are looking for a woman that will do them with a strap-on.

I don't know that it's as uncommon as you might think, just not talked about much.

Dude, so that's actually a thing?! That's even somewhat common...this has made my day. And now I even know what it's called.

Now I just need a guy. And a strap-on.
