Yeah--just going to say... we are in a day and age, where Ladyboys and Western Traps look like better women than the XX Girls. To the point where attractive female celebrities are being bothered about their Birth Certificate to prove they were born female (like Megan Fox).
So, if you are attracted to them... it is because they are just effective enough at looking and acting like real women, that unless you confirm they have a penis, they may as well be real women.
Judging from the original poster, he was not too interested in confirming they really had a penis after a while. What with just wanting oral, some xx girls may have been able to attract him, by trying to fake out being xy girls.
I mean--it is not like he was going, "first, whip out your penis, to confirm ladyboy status, then suck me off."
