If you squeeze (kegeling) in order to delay ejaculation, you actually cause it to happen sooner. Watch your balls. As you approach ejaculation, they pull up tighter. You can actually stay at the “point of inevitability” by having the little lady gently pull on the balls as she strokes you.
A reverse kegel is more than relaxing, it IS pushing. And although not as successful as a testicle pull, once the ejaculation starts, it can be used to stop it before your empty and prolactin builds up, thereby allowing you to cum again (and sometimes again). At least that’s what the book says. I’ve been able to stop the ejaculation, but it completely ruined the feeling for me. Instead,I became addicted to the ol’ scrotum pull.
