Why do you guys stalk women?

I have had stalker situations with a man before and it has changed the way I look at males forever. I am actually petrified. What makes you guys do this?

Is there anyone here who has stalked before? What was your reasoning?

EDIT: Not all men stalk women. I know women can be stalkers too. I AM NOT SAYING ALL MEN ARE STALKERS. I was wondering from a man’s perspective why they think a man would stalk and be able to justify that.
