Sorry but I don't agree with you.
Come on! Who are you kidding?
We all are pervs here.
If you think you are not, you need a reality check.
The OP is neither going out of the way to pry on her nor is he stalking her. She happens to be his neighbor.
Now, if he let a drone loose to capture images of her or face a video camera towards her window, that's a No No!
OP probably thought this is a safe space to talk about it because all the forumers are like him, a sex hound.
But some punters might be cumming in a WL's mouth at one point and then, draw the line on morality when they hear that a guy is curious about a naked girl he sees through his window.
Slam him all you want if he actually acts on it but till now, it's just a harmless fun, which he will forget about when IDK new series of Mandalorian comes on TV or something.
There are way creepier guys out there!
Like this one middle-aged gentlemen in my train line who always watches K-Pop videos.
Does one labelled it as creepy?...yeah, because he is doing that in public in front of girls.
He is not venting his perversion by coming to a sex forum and sharing his thoughts on K-Pop models. Now, that would have been way more reasonable.
