There's a site called "JackinWorld"??!! Hee. I might check that out too, for interest's sake.
Female replying: 3 orgasms each session used to be my 'norm' when I was a kid, and I would usually have a session in the morning and at night. One time in my 20s, I spent a whole weekend masturbating and made myself ill. I had to call in sick on the Monday! Being married, I go thru cycles where I only do it once a month, then once a week. Lately, reading at this site and at Literotica, and writing my own stories, the number is climbing again to at least once a day.
One day (at work!) I did it 3 times, then came home, got to have sex and masturbate some more with hubby watching. I'm horny in my middle-age.
