How important is it to you in a relationship?
Let me explain:
She's fat.
His manhood is small.
People are either divorcing over this or cheating on one another.
Talk to me, im listening.
I will actually give Q a serious answer, at least wrt the mechanics of the situation...
The angle of the vaginal canal varies from woman to woman, affecting penetration. Excess weight in the lower abdomen can exacerbate this, and cause the vagina to cant downward. A fat abdomen and canted vagina can make deep penetration difficult for the average man. Throw in some fat thighs and rear-penetration may be the only viable option. If the lady in question also has business-class buttocks, you can't get there from here.
Excess abdominal fat on a man decreases his effective penis length. Losing 20 lbs may increase the length of a man's stinkhammer by an inch or more. The obvious mechanical interference of a big belly and fat thighs also applies. An overweight man will also likely have problems flying his cheeseflag due to heart and bloodflow problems.
Speaking from a purely mechanical viewpoint, fat is the enemy of great sex for either partner. But a BBW should definitely be looking for a skinny man with an above-average meat dagger. And a slender woman with some sea room between the thighs and a protruding mons venus is a fat man's friend.
