Virtually every man forgets that it doesn't matter how long or how short his penis is, because the vagina will accommodate itself to any length.
- The vagina of a woman who hasn't had a child is only 7.5cm (3 inches) long when she's not sexually excited. The figures for women who have had babies are only slightly different.
- Even when aroused, a woman's vagina usually extends only to a length of about 10cm (4 inches).
This means any penis will fill a vagina completely, unless the guy's erect penile length is less than four inches.
The vagina has the most remarkable capacity for lengthening if something is introduced into it gradually. So a man whose erect penis is over eight inches long can still fully penetrate any woman, providing he excites her properly and introduces his penis very slowly. If he does this, her vagina will lengthen by 150 or 200 per cent to accommodate him.
My wife has never had a problem taking a large penis provided she was fully aroused. It never ceases to amaze me seeing how she can do this.
