I masturbated hands free for about 10 years of my life.

Basically im a guy and I used to grind on inanimate objects and use the pressure on my genitals to make myself have an orgasm. I did it standing up grinding on desks and laying face down grinding on pillows and bath towels. I subtly did it in public settings fully clothed as well. I lost count of how many times I did it at school by grinding on the desks in homeroom while pretending to look down and read a textbook. I was self medicating myself with hands free orgasms every day.
