Yeah, that's where it caught my eye - I just assumed you could expand a bit, but I see what you're saying:
''DLD Push
The DLD Push is a technique to prolong orgasm and remain erect after orgasm. This method involved a hard reverse kegel right at the brink of orgasm. It takes some practice but once it is mastered 4-5 orgasms are possible.''
Guess i just have to make a hard reverse kegel.
