Why am i so unlucky to work with so many pigs!!?

I work for a big company, but it's still no excuse. I've been at my workplace for a year and a half, and already I've laid ual harment complaints about 3 different men. There could have been more, but reminding them that they're married, and that they're being perverts has been enough to deter them, although other women i work with have ended up reporting these guys for haring them. I don't dress like i'm 'asking for it', i know i'm an easy target because i'm quiet and i put up with a lot of @?%�, but why do so many men feel that they can get away with it? I even had my drink spiked by my best friend's father in law, and when i came to my stockings were torn all up the inner thigh- i know nothing happened because my friend started arguing with him and bundled me in the car. On a seperate occasion i stayed at my friend's house and woke up in the middle of the night with her husband half naked and cuddling up to me. He did admit afterwards that he was being drunk and stupid, but still!? Why are they like this? The only men i actually trust are my father and my boyfriend!
