Here are some ways to make yourself pee:

1. Turn on the faucet and/or dip your fingers in a little water to kickstart your urge to pee.
2. Lean forward, pretend you’re passing a bowel movement, or tighten and relax your muscle groups progressively while you're on the toilet.
3. Walk around for a little bit and see if that triggers your need to pee.
4. Rinse your perineum. The perineum is the area of flesh between the genitals and the anus. Sit on the toilet and try to relax. Use a squirt bottle with warm water or a wet washcloth to rinse this area.
5. Use peppermint oil. Put a few drops of peppermint oil in a diffuser or on a cotton ball and inhale deeply.
6. Try tapping the suprapubic area. Go to the toilet and relax like you are about to pee. You need to use two fingers to quickly tap the area between your navel and pubic bone (for women) or penis (for men). Keep beating every second for up to 30 seconds.

I hope this helps!
