I discovered this too. When I was kid I found that out when I was playing on the playground climbing up the support poles for the monkey bars. I didn't know what it meant either until much much later. So yes, I think it's perfectly normal. I mean, basically it's just early stimulation of the clit. Which is supposed to be a very sensitive area.
Good to know I wasn't the only one who made this strange discovery as a kid.
Well if you are hanging onto it with your thighs than it's certainly understandable cause of the proximity of your p****.
It's normal enough, and can happen to guys too. My first ever orgasm was discovered in just such a way.
