Im 25 and the same, always been interested, its my bad fetish sort of thing.
for me its a private thing, at home I will watch gay or tranny porn and be so turned on and never watch hetero porn as it bore me(a vain guy who has a massive ego who thinks hes gods gift urrgh)
I did experiment and slept with men, and honestly it was mind blowing far better than with a girl, but thats as im passive and enjoyed being sexually girly.
But when walking down street I dont have a single sexual feeling to anyone, in fact even on the arranged meets through chat rooms I dont have any interest in the guy until we snog and feel each others body as I get lost in the mood.
Its six of one and half a dozen of the other, im desperate to have sex(give or take or both) with a tranny but its hard finding one without living in certain citys or towns and even then I would have to go on own to the club or bar and thats dangerous.
