I can understand that.
I've been doing this for 33 years.
I almost always get 2 pops in a 1 hour session.
My motivation?
$$$!!!
I want to get my moneys worth!
I stay focused on value for the $$$.
Be sure to Finish up the first pop by the 30th minute.
Then rest for 15.
Then ask for BBBJ. CIM is great, but if she's not up to snuff, ask for lubed HJ.
With ATFs I go for 90 min sessions, and 120s sometimes -- those are even better.
Stay focused.
You can do it!
BTW, do you exercise? Take Vitamins, Magnesium and Zinc?
Stay fit and trim?
It's important!
