This is for sex, period. Putting this baby on is not only DIFFICULT solo, but also not a guaranteed success for the man. I tried both ways, putting it on myself and having my girlfriend put it on me. I almost seriously hurt myself putting it on. When she put it on me, the potential to hurt myself was gone.

This holds your penis more erect, and grips the testicles, keeping you harder longer.

It's a stretchy material and I believe it's silicone. No real odor. For the male side, there are smoothed bumps that both stimulate, and also help grip on to the guy's junk. The side facing out has more... I would describe them as something like spikes. But they're not painful, they are very stimulating for her. Coupled with the vibrator, this ring is the poster child for stimulation.

It's well designed and good for both parties of the couple. The vibrator, bumps, and spikes are incredibly stimulating and useful for both partners. It's stretch allows for adjustment. Not easy for a man to put on himself, but once on it feels excellent. It reaches all of the necessary areas on both parties. The stretch factor allows for fitting to the average person. Anyone with a larger package will benefit, but if a man is too thin, he might not experience the full effect.
