"You have a boyfriend, you want to keep him happy, you want to be able to suck his dick right, then you learn how to deep throat. The only thing that can stop you other than gag reflex is if your teeth aren't far enough apart in the back. If the guy is too thick to get past your back teeth, then there's nothing you can do. Bigger is not always better. I feel bad for the guy because the girl can't get his dick past the back of her, but there are other things that make blowjobs better besides the whole deep throat thing."
