Don't worry so much about size. The part of a female that creates the most pleasure is only about 1 1/2 inches deep. Plus having a pens too large has issues as well. The average woman is only 5 inches deep so anything larger has the potential to cause some extreme pain. The average male is 5.51 inches so it should be a good fit either way. The key is to make sure she is satisfied first then you can be. If you do that then it doesn't matter how big you are.

Its not important....I think you can have fun with most size cocks. After all its not the quantity its the quality! Even some blokes with massive cocks dont have a clue how to use them! and it all depends how much or how little you can take! just enjoy it!
