Public Masturbating

Its rude to point at someone, its ruder to stare at someone. Spitting at someone is vile and reserved for only the classiest of folk (train station dwellers.) But an all new low... and a rudeness with its own community of rude is masturbating at someone. What does one call this activity? its not flashing, its not molesting its masturbating at someone. Some characteristics of a extroverted masturbator is the inability to walk, they lurk. The inability to sit still, they shake- not a scared shake, more of a cold shake (imagine a whippet) They have strange sleeping hours, almost nocturnal.
One freezing cold Melbourne morning my sister left our house to go to work, she was doing the breakfast shift at the local cafe. She briskly walked to the tram stop to read the timetable. My poor innocent sister noticed the shadow of a lurker but thought nothing of it as she stepped into a doorway to keep warm while waiting for the tram. That's when he struck. Around the corner popped the pathetic excuse, pants down, dick in hand, desperate look on his face as he started to masturbate towards her. My poor sister ran all the way to work. Mortified.
Now I'm not naive to the fact that men love there dicks. Nor do I think I'm the only one who's been in the following situation......
Girl gets drunks, girl meets guy, goes home with guy, gets into bed and realises shes to drunk and not into it so opts to pass out instead. (Come on we've all done it) Funny part is when guy gets desperate and after trying to wake the girl up for 15 Min's realises he has to take matters into his own hands and proceeds to wank right there in front of her.
Orgasms arn't the only thing we ladies fake, we also fake sleep. So cheers for that one fellas doesn't leave us feeling awkward at all!
When I discussed this scenario with a girlfriend she admitted shed been there but didn't think there was anything wrong with it.
Anyway I'm not that understanding, I don't see it as a mans need to get off or a beautiful thing. I don't feel the need to celebrate a mans cock at every opportunity nor do I see his orgasm as an imminent ceremony.
To me these acts are desperate showcasing a sexual greed and lack of control. But a lack of self control that Iv learnt to tollorate. Should have just coughed up for a cab home.
The real villains in the story and the public masturbator... The train station wanker, the guy on a date with himself in the sand dune and the cinema creep camouflaged in all the different shades if fowl.
So after carefully reminiscing the time I almost bumped into a guy doing a poo under a statue in Madrid and the overweight, half naked hooker that looked to be halfway through her menstrual cycle on high rd Kilburn- Iv come to the conclusion that if you places public masturbators in a community with all the above and worse they would still find themselves the guy in the town being referred to as 'The Rude Guy'
