I completely agree with juslee69!! :D
I've sucked a friend around 200 times (for about 4 years :P) and he have sucked me (he is incredible by the way... he really liked it) ;D ... but somehow he is still str8! :P... Now, he lives with his girlfriend and probably thell will marry soon :O
(sorry for the English :S)

i've sucked my str8 friend couple times..but i didn't turn him into gay..or bi...he just let me suck him till he cum in my mouth..and never talk about it at all the day after..but when i sleep over..i know he want to do it again.

What a fantstic cum load, would love to do that to another guy, especially if he was straight.
