You do not push your breath out. No Poppers when doing this.
Takes practice to do this.
Take a slow deep breath in and relax.
Getting close to cumming? Do the Kegel on breath in and relax all.
Takes practice but it will be worth it as you will have stronger orgasm.
Although I recommend you do not cum every time. Try every other day for starters.
One day one do all you can and enjoy, but do not cum. Save it for day two.
Over time you could last longer than 1 hour or 2.
It is amazing. You will see in the videos I have made which I was able to the men last awhile.
