How can you expect oral when you dont give it? Id expect anyone who enjoys oral wouldnt be keen on giving to someone who wouldnt reciprocate.
Chris Rock said it best, "I look at girls who dont give head like a betamax. 'They still make you???'"
And about guys who dont go down, Chris Rock said this "If you aint eating *****, youll lose your woman faster than your house keys. 'oh damn...where did she go. I just put her right here a second ago'."
Real talk. Dont expect to hold onto many women if you dont go down. For a lot of girls, its their favorite part of sex, and some can only get off from oral. I call people who dont give oral sexually boring and would not be having sex long with a girl who didnt give head.
