Sorry now
At the time it was arousing but now almost 15 years later its become embarrassing each time I see girls I grew up around. Some were my age at the time between 14 and 17 but some were also younger. I was so obsessed with exposing myself it got out of control. Those girls are women today, friends with my sisters and 1 who now works in my wife's office. As a teenage all my sisters friends saw me naked numerous times and many watched me masturbate or just make a compete fool of myself. Both my parents worked so my nudity at home was blatant and ignored by my sisters. Their school mates and neighborhood girlfriends saw me naked or partly naked on a regular basis. Outside the house I was successful at the rec. center, mall, beach or park wearing shorts with no underwear. I think I made a big mistake moving back home last year because many of the these girls are still living here and I see them everywhere I go. So far only 3 have mentioned it to me but I know by the looks from others that they didn't forget about it. I feel myself blushing when I see some of them and especially when I talk to them now. It was arousing and seemed like fun at the time but now its humiliating whenever I see one of the girls I'm sure had seen me naked and more so if I remember them seeing me masturbate.
I get that it's humiliating, but does it also turn you on knowing that they've seen you naked?
