Male Rings & Condoms
The ring goes between his genitals and the rest of his body. His penis and balls go in front of it. A good tip is to put one testicle through the ring then the other and push his penis through last. Some men say that the ring makes the orgasm more intense and some men cant orgasm with the ring in place. Work out what's best for your man so he can rip it off when the time is right.
