Though I don’t get these myself, from what I understand, erections are all about blood flow. Blood flows in, penis becomes erect, blood flows out, things get a little droopy. Unfortunately, tides change frequently and are hard to control. However, cockrings are one great way to keep the boat rockin’.

Cockrings are solid or adjustable rings usually worn at the base of the penis, behind the scrotum to constrict blood-flow to the shaft and head of the penis, increasing pleasurable sensations of pressure and that tightness you boys are always raving about. For some, this can lead to stronger orgasms and firmer or longer-lasting erections, but these aren’t the results for all, nor is this (eureka!) the cure for erectile dysfunction—you’ll need to check in with your doctor about that one. (Speaking of doctors, because cockrings play with blood-flow and sensitive nerves, don’t use them if you have a blood-clotting disorder, are diabetic, suffer from any kind of nerve disease or are taking blood-thinning medications.)

So you’re looking at your very impressive second-in-command and then you’re looking at a ring that appears to be some kind of baby’s bracelet. Not adding up? In the case of solid cockrings like those made of metal or wood (see stockroom.com)), the trick is to put the ring on before aforementioned commander reaches full-salute. Yes, you do want to make sure the blood is flowing in the right direction before locking it down, but the only way to get a fully erect penis into a cockring is a painful one. At a little less than half-mast, start with tucking the testicles (one at a time) into the ring before gently pushing the shaft of the penis through. Until you get used to rings, only wear them for increments of five to 10 minutes, (20 minutes maximum) to avoid discomfort (at best) or erectile tissue damage (at the painful worst). When flaccid and ready to un-ring, simply untuck.

Sounds easy? Well, rings are hardly one-size fits all and finding a proper fit is essential to avoiding damaging mishaps or discomfort. While a ring’s tight squeeze may feel comfortable when you’re soft, the harder you get, the tighter the ring. More important, once erect, there’s no getting that ring off. (Stuck between a ring and a hard place? Try an ice pack, cold shower or lots of lube.) Luckily, those solid metal cockrings you may have seen around a pornstar’s money-maker, though sexy looking, aren’t your only (or best) option.

First-timers have done well with leather snappable cockrings as they still manage to look tough wwhile having several different snaps along the ring’s length that allow you to comfortably adjust or simply unsnap. Another beginner-friendly material is elastomer or silicone used in stretchy cockrings like the RingO (babeland.com). Though not adjustable, these user-friendly options stretch to fit, providing a firm squeeze and easy removal.

To shake things up a bit, opt for vibrating cockrings, like those found in Screaming O’s line of stretchy soft-gel rings designed with small vibrators strategically placed on their topsides to give your partner something else to moan about. Try it out with the cheap, disposable Screaming O, or double your pleasure with the Two-O—it has a vibe on top and bottom for a little ball-buzzing—or the Bong-O, whose small, hanging bead adds pleasurable percussion to your rhythm (thescreamingo.com).

Don’t get too cocky—vibrating rings can stretch around all sorts of things, so get creative. Wrap one around your fingers for some clitoral or anal stimulation with your digital penetration (fan-favorite Neptune Ring has a separate controller so the receiver can control the buzz, goodvibes.com). Put one around a dildo, either facing your partner or on the inside of the harness facing yourself. And don’t shy away from those with larger vibrators like Good Vibrations’ Cyber Ring—the larger the vibrating surface area, the greater your chances of hitting your mark.

Longer, stronger erections with longer, stronger orgasms and extra vibration stimulation! Now that just has a nice ring to it.
