I have a very strong and healthy cock that totally does the job, made 100's of people happy and even into returning customers - made some guys cum hands free and got my wife pregnant 3 times.
Yet, i am still concerned sometimes with my size when i am in tight speedos with friends or fully nude in public. It's when i see much larger guys nude that my confidence gets weaker sometimes haha...
but then again i say to myself that all is good, i remember my sexual abilities and i can be a proud man no matter my size and show it off!
