Some urinate on my jeans without cumming or fapping?

Maybe is precum. When I get aroused I produce quite a bit. This is from the internet.

Pre-ejaculate, sometimes called precum, is a clear fluid that is released when a man becomes sexually aroused, but before he ejaculates. Sometimes, it can be seen at the tip of the penis, but many men don’t even notice it.

The fluid is produced by a pair of pea-sized glands called the Cowper’s glands, located near the urethra, a tube in the penis with a dual purpose: allowing urine and semen to exit the body.

Pre-ejaculate fluid neutralizes any acidity left by urine in the urethra, protecting sperm that flows through.

 

I won’t count it as a relapse. For sure a warning that you need to stop entertaining those sexual thoughts.
