Crushes!!!

Honestly can I say something that will offend you guys...in a way that will make you laugh also...
Why do I have to have a CRUSH on everyday people, and it happens all the time, no matter where I go or where I am, if I look at any given direction and if I find that guy handsome, I already have a crush on him.
I still don't understand why do I need to have this fixation, and at times it also drives me crazy.
Has anybody gone through a similar thing?
Let me know!!!
