I have spoken to ladies about this and the following was established - Size does matter- a 3 or 4 incher is not going to cut it for the ladies.
If lads put as much thought into technique as they put into worrying about the size of there cock it would make a lot of women happy . old chinese proverb ( long and thin goes a long way in. short and thick does the trick ) .
there lot off chat here about size and how two used it , it down two getting it on .....
