lol.. they ARE JUST AS HORNY ~~ really!
I have alot of similar experience like Caesar95's. Dont believe u can try this little "test".
There was once, in a crowded bus I was sitting on the "outside" and i fell asleep. Then suddenly the bus made a sharp turn and the girl standing beside me knocked onto me and her groin area was pressing hard against my shoulder/arm area. She was definitely very shocked and maybe embarressed and very quickly pushed herself away. It didnt really bother me and i tried going back to sleep. After some time, i noticed she started pressing herself against me - slowly touch abit and then away for a few times, and then later she stay pressed against my arm. Slowly i realise some slight "motion" going on. She tried to "rock" left and right slightly along with the motion of the bus. She kept at it for a VERY long time. Of course I act as if nothing happening to see how far she'd go. When i reached my stop i stood up and looked at her - she's quite a decent and sweet looking girl. She looks abit embarressed, maybe still wondering if i knew what happened. Would be good to have as a GF

After this incident, I tried this little "test" many times - and it works very frequently. Many times they will be shocked at the first "contact", but after that I'm very sure they would "come back". Kinda weird habits these girls have XD The thing to note is that I always sit low, and probably abit more "out" if i wanna "test". And also, must pretend to be unaware, so the best way is to act sleep. Of course must be a crowded bus la, and abit of luck that a girl will stand next to u. XD
