And where did you get your information from? From female porn skags who are encouraged and paid to practise bisexuality for the purpose of pleasing sleazy straight guys? Looks like it.
Face it - male bisexuality is a simple biological fact. No amount of denial by straight porn dimwads is going to change that fact. You scuzzbuckets in the straight porn industry have a gall to deny the existence of male bisexuality. Almost all of you are pathetic losers with the IQ of rancid cabbage.
