Cock rings are simple devices that help to maintain a harder and longer-lasting erection by restricting the blood flowing back down your penis, which in turn makes your enjoyment last longer and orgasm more likely. Some people choose a cock ring that is worn on the shaft, others like the feeling of a cock ring that goes around the penis and the testicles. This guide will tell you how to measure yourself for both kinds.

Cock rings are measured by diameter. This is the measurement across the widest part of the hole in the ring. You want a cock ring with a diameter that's smaller than your personal measurements - this will ensure you have the constriction that you need. Start with something just a little smaller than your measurements, because the smaller you go the tighter the cock ring will be.

Most cock rings are adjustable or have stretch to them to ensure a good fit, but to be sure it will fit perfectly you need to find out the diameter of your cock or cock and balls. You may be wondering how that’s translatable to your very 3D penis, but it’s easy to calculate and we'll show you how.

Lots of men decide to try using a penis pump to achieve a larger manhood in minutes. Bathmate penis pumps use the power of water to help you achieve a bigger length and girth.

A question we get asked a LOT at Lovehoney is "how can I make my penis bigger?"

Now, we like to remind people that bigger doesn't necessarily mean better, and it's often better to learn some tips and tricks to use what nature gave you.

There's a lot of truth to the old saying "it's not the size, but what you do with it that counts".

But for those penis-owning people out there who want to boost the size of their boner, there are several ways of doing so, for both short and long term gains.

If you hunt around the internet (or have a peep in your junk emails, for that matter!) you'll trip over dozens of ways to increase the size of your penis.

However not all of these methods are particularly safe or reliable (bee stings anyone?!) and some can even lead to shrinkage later in life, so it's really important you do your research and choose a safe way to magnify your meat flute.

In this weeks video guide, Jess and Annabelle tell you 4 sure-fire ways to do exactly that!
