I’ve become obsessed with this. I want to learn more about it. I tried it on myself but was unsuccessful
What did you try? I decided to revert back to i years old and played with earthworms. It was whimsical but left me determined so i made that a must do item. There are tricks to it. Taking a dose syringe with cold mildly saline water and flushing out your penis does marvels as does using a straw and feeding the worm iij nto it at top end and inserting bottom end into yourself.
When you do this have a cool wet wash cloth on your penis. Earthworm will go in and wriggle around. Its wildly different. Afterwards a gave them a rinse off and put them back outside.
Maggots are more fun and you can by them online in several forms. Dilating your urethra 1st is a must, then getting the maggots into a narrow straw and pushing them into yourself using a make shift plunger.
Its all a bit weird but can be fun.
Ive played with urethral stuff for around 4 years now. I find it helps with narrowing of the passage from prostate growth. Doctors also do this for same reasons.
I once tried an e stim sound. It inserted into the penis about 5 inches while a metal plug inserted into the anus. Borh are wired to the control box.
Current takes turns running from penis side back to anus side front. It was crazy good. -
