So I've been living with varicocele for almost 20 years and I've tried many things to alleviate its symptoms. I've also been experimenting pain after ejaculating. One day I wondered what would happen if I jerked off "against gravity". Let me explain.
Before getting into details, know that I have no scientific proof for this, just my experience.
I'm sure many of you know what milking from behind is –for those who don't, you're on all fours and someone else (or yourself) masturbates you from behind. Now, instead of standing on your arms and legs, rest your head on an arm or the bed/floor, however you like. Just make sure that your pelvis is higher than your head, so it helps fluid draining. This is essential.
I tried it a couple of times just for fun and realised my balls were hanging considerably less, so I made it a habit and began doing it 1-2 times per week (of course it's more fun if someone gives you a hand :P). The post-ejaculation pain has almost disappeared and the size of my ballsack is the same as it was 15 years ago, before the surgery and before those years of extra blood pressure.
If you're curious about it, try it out for a few days and let me know if it works for you, because any case is unique in its symptoms. I hope it does and, if that's the case, spread the word so we can help other men.
