Is it normal that i like others to see me touching myself in public?

Sometimes i find myself wanting to expose myself in public to people. Like i want them to see my dick. I sometimes put myself in those positions so people can see me do that. Like pretend im changing down at the beach in my car and an older lady will pull up next to me and catch me changing and she will see me completely naked in my car. of course its staged by me.

but is this really weird? do other guys imagine being out in public and having a girl see your exposed or touching yourself in your car? I dont mean grabbing/flashing your junk to some hot chick walking by. I dont think its bad, but i know that it could be indecent exposure or something. ... any suggestions?

Another time that made me realize that this might not be normal was when i was in a parking lot and I was pulling through the parking space to park. on my way into the spot I saw that there were 2 younger girls in the back seat and I had to wait a sec for the parents to get out of the car. once they left i parked my car next to theirs. just like anyone else would but bascially our cars were facing the opposite direction so their backseat could see perfectly into my front seat. So i started touching myself and i could see them watching me. my heart was racing so fast it was actually hard to even get my dick hard. so these girls are watching me touch it when it was small. eventually i got it hard and ready. About 5 minutes went by of them trying not to make it obvious that they kept peeking over at me. then i twisted a little bit so they both could see me completely exposed and i jizzed all over my stomach again. and right as my body was quivering from an amazing orgasm. they got out of the car starred at me for a second and ran into the store.

I know that when im down at the beach and i see a girl changing in her car and i happen to catch a glipse of her boobs . that basically makes my whole day if not my week. so is it really weird or normal?
