I am in my early 30's and I generally refrain from masturbation for 3 days. I suppose the longer you abstain, the hornier you get. Wonder if there is any specific science to it as I notice it kind of comes in waves.

Under ideal circumstances, three days of holding off in your early 30's, and you should be bouncing off the walls horny.  That's true regardless of age, so...

The LG has a entire program for max performance.

The same ones that women use to strengthen their stomachs after giving birth will be perfect. Start with a low number. Increase the number as your lower stomach become stronger. And drink water as much as practical.

In the end that is ALL THAT MATTERS.  She is NOT falling in love with you.

Kegels for men.

I'm 36 and I mastrubate everyday somtimes multiple times a day and I can still give them a  good run. Maybe I'm just a big hornball but, don't worry about that. Its all about you and your satisfaction. They just want your greenbacks, the faster you finish, the better for them. Don't go with a weeks worth of man gravy built up. You'll pay for an hour and blow in 15 minutes. Some will try for a second but if you can't recover in time its on you. I learned how to control my pops by learning my body. I can pop in 2 minutes if I want or I can really f&c% the shit out of them for an hour.
