I've been straight my whole life but recently I've been watching transsexual porn do you think that means something
In my opinion I think this means you are curious. Nothing more, nothing less. There is NO JUDGEMENT placed on curiosity.
No idea. Like brainwashed said, you're at least curious. Do guys turn you on? Does the thought of hugging/kissing/more with a guy arouse you or disgust you? When you go to the beach, who are you checking out? Whatever your sexuality is, feel free to stick around.
Shemale porn is one of the most popular genres on the internet now. It is also far more common among the straight population than the gay population according to statistical surveys (sorry, no link) because this site frowns on links.
