Voyeur Addiction?

Can anyone be voyeur addict? In the house opposite to my home, one girl stays who would go to bed every night by stripping her cloths off. I never intended to see this but accidentally I saw once and it repeated over few days. She doesn't know that I can see or she must be careless. But now my brain wants it every night n for some reason, if that girl is not home for sometime, I feel completely uncontrolled. I always thought why doesn't she close her window before she goes to bed but she keeps it open.
How to come out of this? I know this wrong and even legally it is not right.

You can be addicted to MANY types of porn - read an article in Japan about a guy who can only get aroused to nude robot women who look like power rangers.  :

If the girl is doing  intentionally and gets some excitement from it then that's none of your business don't you agree?  The fact that she's done on consecutive nights tells me she get some pleasure from it, so what?  If you view her somehow either inadverentfully or on purpose it is okay as long as you do not act upon it evilfully assault, rape etc.  Who's business is it to question how anyone dresses or undresses?  The lady is making herself an object for some reason, but why is not our business, controlling ourself is OUR business.  It's a free country and we have the right to make our own choices and that's genderless.

Don't know if I modified my message, meant to say "do NOT act upon it evilfully"  :-/

I wouldn't say it's particularly damaging. Juvenile perhaps, but that's about it. In terms of affect on the brain, I'd say it's about the same as checking out an attractive girl on the beach.

There's no complex answer for how to stop it though. Just stop. Close your blinds or just don't go to the window. It's like asking how to stop watching a tv show. Change the channel or turn it off.

You could also just try talking to her at some point. Not necessarily ask her out; just strike up a conversation. If she turns you off, that may help things along.
