Naučni vodič za dugotrajnu ejakulaciju - serija treninga izdrženja

Hey guys, it's Blair. Today we're going to be doing part 3 or 4 of our stamina challenge

for the month of July 2022.

The goal is by the end of these videos to have a better understanding of your orgasm

and hopefully help you increase your stamina gain, whether with your partner or in your

quest to master masturbation.
