Hi all. I am a fourteen year old girl. A few years ago at school during gym class, our group had to do fitness testing. One of the tests was the flex arm hang. (That is when you hold your chin above the bar for a certain amount of seconds.) Well, I was up and i was at about the 15 second mark when I felt really tingly and whatnot down there. So I went home and did the flex arm hang again and I got that same sensation down there! So weird. I have been able to do this for about three years now. Is it normal? I read only about 5% of woman can orgasm while exercising. Thank you all! :)
