The diamo reviews on Amazon are a bit of a mixed bag… https://www.amazon.com/product-reviews/B08H8HS5X3/

A few people report no being able to put it on as too small, but I suspect it’s more to do with their inexperience of feeding your balls and then cock through a confined loop.

I’ve used chastity so have no problem, at first until you find the technique you can conclude that the opening isn’t big enough.

Tip: make sure scrotum loose, holding the loop below your balls, pull the skin so that one testicle comes through the loop and push the opening up further to make space for the next. Then push your completely flaccid penis into your scrotum, like trying to make it disappear, then let it come back out on the other side of the cock and scrotum ring.

Yes, the Lovense Diamo is a good sex toy, not only for a cuckold, but anyone who is seeking a remote controlled penis ring that can be worn for play alone, in the bedroom as a couple for foreplay or during sex, plus app-controlled for long-distance sex toy play for partners apart.

I've posted my review on the Lovense Diamo which should help you decide for yourself if you consider it good or not.

As a closet cuckold I have been searching for sex toys that can help me explore cuckolding with my wife without actually admitting my fantasy to be a cuck, so I am really appreciate you sharing this post and sex toy.
