If the testicles are in the way, gently push them out to either side and position the penis between them.

If it hurts or you start to feel nauseated, stop and take a break before trying again. The testicles may naturally pull up into the inguinal canals when you’re cold. It may help to sit in a cold bath or shower for a few minutes before you start.

Pull your underwear up firmly to make sure everything stays in place. If regular underwear doesn’t give you the support you want, look for control-top briefs or shapewear. These types of underwear are made to smooth out bumps and bulges under formfitting clothing.

For example, some gaffs have simulated camel toe or built-in rings to help keep your junk contained. You can usually buy a gaff in the same size as your regular underwear. If you’re not sure, though, check the seller’s sizing information before you buy a pair.

If you need more support, slip on a tight pair of underwear over the gaff.

You can always reinforce the tuck by wearing a tight thong or gaff under your swimsuit.

Look for a dance belt online or at a local dance supply store. [8] X Research source This is a great alternative option if you find tucking uncomfortable.

This is also a good opportunity to go to the bathroom or just give your junk a chance to “breathe” a little!

After you tuck, always examine your genital area and look for any spots that look pale, blotchy, purple, or blue. This kind of discoloration is a sign that your tuck is too tight and has cut off blood flow to the area. If you see it, untuck right away and try again. To minimize the chance of hurting yourself or getting an infection, it’s best not to stay tucked for more than a few hours at a time. Take frequent breaks if you plan to stay tucked all day. [11] X Research source Be careful not to tuck for too long. Staying tucked for more than a few hours at a time can increase your risk of health problems such as bladder infections, skin irritation, circulation problems, infertility, or torsion (twisting) of the testicles.

Go to the bathroom right before you tuck. [14] X Research source Take pee breaks at least once every 3 hours, or as often as you feel the need to go. [15] X Research source Spend time untucked as much as possible to give your body a break. For example, avoid staying tucked when you’re at home or when you’re sleeping. You might be tempted to drink less when you tuck so you don’t have to go as often, but drinking too little can cause dehydration. Stay healthy by drinking about 4–6 cups (0. 95–1. 42 L) of water per day—even when you tuck.
