It's a really common question, and given most sex-ed classes tell guys that condoms are "one size fits all", no wonder so many men want to know the answer.

How did you find the right size of shoe? You had to measure your feet.

How about your shirt? You had to measure your neck and chest.

By measuring up first, you were able to find shoes and shirts that were really comfortable to wear, right?

Exactly! To get the perfect size of condom, simply measure your erection. It really is that simple.

We guarantee that we can get you the perfect fitting condom, or we'll give you £10. Guarantee? Yes - if you're not completely blown away by your TheyFit experience, we'll give you all of your money back, plus another £10. Are we crazy? Maybe. But we also know that our custom-fit condoms are the best fitting condoms in the whole world...

Step 1 : Measuring Up

Two measurements are necessary to get the perfect fitting condom - length, and circumference (also called girth):

Length is important to make sure the condom covers the whole of your shaft. If the condom is too long, it's going to bunch up at the base, which looks odd and can act like a tourniquet (rubber band) causing tightness. On the other hand, if the condom is too short then it's not going to cover you fully, and may be pulled off during sex. That's clearly not a good thing either.

Circumference is important to make sure the condom stays securely in place during sex, while still being comfortable. If you try to use a condom with a circumference that is too small, the latex is going to have to stretch too much to fit you. That will lead to a feeling of tightness, which in turn may cause you to lose your erection, or have difficulty reaching orgasm (most guys report not being able to feel anything during sex - this is caused by the tightness). On the other hand, if the circumference of the condom you tried to use was too big, then the condom will be loose and could slip, or fall off entirely. That's bad too!

Step 2 : Try TWO custom fit condoms

1. Measure up as per step 1 (easy instructions here)

2. Choose which Sample Pack you'd like to receive here

It's as simple as that. TWO custom fit condoms will be sent to you to try out.
