For many people who are in Femdom relationships, the man is also in some sort of chastity or orgasm control. There are many where the woman still wants penetrative sex from the man, but does not want the man to orgasm etc.
I found this picture of what appears to be an interesting way to solve the problem. It looks like a thick dildo that goes over the cock and balls, almost like a cock-ring, but then the penis is encased inside the thick dildo. It looks to me that it allows the man to fuck the woman with the dildo, but not feel anything. All without the need/use of a strap-on.
Unfortunately, I did not find this on any toy store. Has anyone seen this before? Do you know where to get it? Any reviews of it?
