Meh...size has nothing to do with being able to please a woman anyway...unless you're really tiny down below. Confidence is the most important thing when it comes to sex. If they know you know, you know how to use it to their advantage, that's all that really matters.
How did you come to such mastery of ejac. control? Kegels, or just doing it often? I've founds kegels to be very good in this department and also regular use of the bathmate.
