When it comes to sex toys for men, a cock ring—or penis ring—is one that should be at the top of the must-buy list. These usually-stretchy silicone rings are made to go around the base of the penis (and often around the balls as well), creating a constrictive effect that allows blood to flow into your dick as you get turned on but prevents blood flow from leaving too easily. The result is a harder, more sensitive, long-lasting erection. Cock rings may also result in significantly stronger orgasms by delaying ejaculation for a more intense climax. And for folks with erectile dysfunction, a cock ring—when used in addition with ED medicine—can help them stay hard even with just a partial erection.
