The round shape seem very compatable more for a woman that any use for a guy.
I suggest you check out some of the reviews there on the product page, toward the middle when you scroll. It is made for external genital stimulation or you could use it on other parts of the body for a normal massage.
On second thought it would definitely get lost, there's no string
Good luck even using it anally. I don't think you guys realize how big this thing is. I know, it's hard to tell from the pictures and you wouldn't ever guess. But it's actually got a circumference of 10 1/4". It's huge.
