You are joking for no reason.
If you are here for long, you should know the answerto the question, size means nothing, its the skill of a person that makes all the difference.
Having a 3.5 inch dick guy can be a much better fucker than a guy with 9 inch who doesnot know how to use it. Its the flawless technique that matters, not the size.
And next time before posting, please check the scale again, I guess you went through the centimeter side of a scale instead of inch side.
