Mixed up sex.

yes, if the chick with the dick was fucking the real chick then no

but this dude is 1/2 way through a sex change ... if he was a full female wouldnt that be lesbianism ?

if it had a full change (no penis) and was still taking it up the ass it would no longer be gay, but it wouldn't be exciting either

if its sex between a man and a woman it should be hetero no matter what act they may be partaking in...

^Takes it in the ass and doesn't care who gives it to him.
