Well in the UK I have only shot with 2 men that do Gay porn... All the other men i have shot/shot with are first timers....
Most guys i come across are basically Bi/Bi Cur and pretty comfortable around TS/Guys...Hell they get paid so as the saying goes Gay for Pay :)
Judgement on them, dont really have one..myself i dont like labels of gender/sexuality i just think we are people, and if someone is sexually attracitve to you, gender/sexuality are irrelevant.
