an elastic ring which fits around the base of the penis. It constricts the veins which drain blood from the penis, thereby strengthening an erection. Bought cheaply in automotive parts stores as "O-rings", they are black in colour. Also available in sex shops which sell vibrators, condoms, etc.Also increases the sensation during ejaculation as it constricts the urethra.
I had been having trouble maintaining an erection with her, as I was very nervous. We had some wine, which helped, but then she cut the end out of a condom and rolled it backwards onto me, forming a cock ring at the base of my dick. After that, I had no problems.
An instrument used to squeeze the penis and the balls together. It produces an immense sensation of feminization which any masculine individual really serious about sex and love should entertain and meditate.
The day when every man will use regularly a cockring will be a day of cooler, calmer and more respectful mutually enhancing sex.
