It's not about the size...Ughhh... why does a guy put too much emphasis on this subject?
Everybody has different peak time and not all everybody are created equals.
Your time is NOT considered too short,
As most guys do get about 15-20minutes for one session!!!
Don't be fooled by what you read in the novel...
It is written base on some fantasy ... that a REAL man must be able to withhold for more than an hour!!!
Also, how about your partner? if you want to be a warrior & keep going & going ...
Do you ever wonder ... if she can handle that or not?
The key to a perfect balance in your sex life is that you & she are well balanced.
As some ladies won't be able to handle more than 15- 20 minutes anyway.
Another misconception from most men is... that most ladies want it more & more...
That is totally NOT entirely correct...!!!
As most ladies can not/will not be able to have multiple orgasms & that is perfectly fine as well...!!
My point is that as long as BOTH of you enjoy it AND it is a perfect balance...
You don't have anything to worry about...
