How can I make an ADS without cutting circulation?

I wanna make an ADS that I can wear indefinitely, with a very strong tug. What I’m trying to figure out tho is this- How can I make an ADS without cutting circulation? I know I’m probably gonna have to have at least some of the penis-gripping end of the attachment apply some pressure towards the inner penis and not just friction on my shaft, so I don’t just stretch skin. I want it to always just be there, kind of like braces..

Options I’ve considered (VERY open to suggestions)

-Something that applies good pressure, but only to the sides of the shaft. It’ll be kind of like the BibHanger, but my problem is- I actually have owned a BibHanger, and I know those things cut circulation fast, ESPECIALLY if you get an erection, which is always a possibility.

-Something that just grabs/sticks to the glans. This could work, but with erections spontaneously inflating/deflating the glans as well, I just don’t know what kind of adhesive can tolerate that kind of surface variance. A noose would definitely cut circulation. Also, I imagine something like this, if successful, could lead to some really ugly looking gains

-A vacuum, maybe like the Phallosan. My problem is that with the forced I want to use, the vacuum would probably have to be so strong it would probably eventually cause blisters if used extensively

I’ve tried using Tom Hubbard’s jelq sticks (one at the base and one behind the glans) and a compression spring. It was kind of weird, but I liked it. Also, there is the biker ADS…it is very cheap to make.
