I did 12 weeks of beginners programme. Not totally JP's programme but basic exercises only. Then I had a week off and now I have moved on to more advanced ones which focus more on girth.
I also thought that if it works, don't change it. And my basic programme worked really well! But then I had sex and she told me that I am big for her. So I decided that maybe I should slow down with the length and focus more on girth because I am still under the average. That's the reason for changing the programme.
First advanced measuring day is in a week so we will see how it works.
Longer foreplay and screw slower. She will adapt to your size, use a oil basre lube if you have to for easy gliding. mineral oil would be good for this it is tasteless and sentless.
