As Red said increasing the weight when doing Kegels will strengthen your pelvic floor muscles very quickly. So using a towel or a book and draping it over your penis while it’s erect and doing Kegel raises you’re going to really strengthen those muscles. Benefit of those muscles being strong include much harder erections, more control in bed, make multiple orgasms and much more.
Reverse Kegel inside a penis pump? @DLD, isn't the normal Kegel the right thing to do while pumping? Reverse Kegels seems to work well for length. But I am seeing some sense in what Big Schwanz is saying. Too much kegels inside the pump has caused me weak erection in the past so maybe it is best to balance it by doing Kegels and Revere Kegels while pumping. What are your thoughts?
