I became curious about this question yesterday and can't find any answers on the Internet (at least through basic Google search), so this seems like a fine place to come and ask. When a girl's mouth is open and in preparation for giving a blowjob, I wonder what the distance is from the mouth/lips/teeth area to where the throat starts or where deepthroating would begin (on average, of course). Basically, what length of dick would a guy have to have probably for it to even be possible for him to be deepthroated?, because I'm sure some guys are too small to even be deepthroated by a girl.
5 inches for me, however i can't deepthroat properly unless he's 7 inches or more, cause it can't stay comfortably past my gag reflex.
Entiendo. I suppose an acceptable way of measuring it is for a girl to stick her finger in her mouth and see how far she can get it before it hits her throat/gag reflex then measure how long it was on her finger. My friend got to her knuckle. So there's two statistics for this wonderful scientific study, lol.
