Physics of an erection

I was going to ask the question "how does a ring cause/maintain an erection?", when I read this statement: "[cock ring] constricts the veins in the penis, but not the arteries. This means blood can flow into the penis, but not out; allowing for a healthier and harder erection".

Sounds reasonable, so it passes the first "but I read it on the Internet" test. - Mike

Wow! I am working on my PhD in ED and I find your statements very enlightening. This article appears to graphically support your theory (https://www.baus.org.uk/_userfiles/page ... iology.pdf).

I have a VED gathering dust on my bathroom shelf. It came with a cock ring which I have not used. It's time to try it out after my Trimix injection and validate this theory.

I've found I can make a serviceable ring with latex tubing formed into a 3/4"-1" circle and held in place with a small zip-tie. Mike

I'm assuming the tubing is stretchable? Otherwise I would advise do not use!!!

If I used that thing and it was not stretchable with Trimix, I could see ending up in ER with them having to cut the thing off.

Reminds me of the lasso type penis rings that you can find on Amazon.

Did you make the ring adjustable, or does the zip tie bind it up too much?

Not adjustable, but I could easily add something like a large bead with a hole in it to make it so. Or simply drill a hole or two in a dowel to get the same effect. Takes less than 5 minutes to build one, so I have a collection. - Mike

That type of lasso doesn't work for me - tried many different ones. I only have luck with rings that are designed to put pressure on the veins to retain blood (i.e. Erecaid)

Did you ever try the type of ring that goes all the way around your whole package?
