Never had any action until early 20s, definitely late starter, not for want of trying though... Although, when I was 14 there was a 14 year old girl I went to the park with, she put my hand down her panties and asked me to rub in very specific places, which I did, after some time she started to get all tense and held her face in her hands sitting there. I was worried and said was she OK, she said shutup keep rubbing don't stop - then she froze up for a few seconds then went all pink. My mate of 12 was sat there the whole time with us, he was as startled as me. When she regained her composure I said what happened, she said oh nothing just a fit. Never did figure out what happened there....
