I love to spy on my roommate while he showers.
That's awful! Why would you spy on them?
I enjoy peeping on people when they don't realize it.
Your roommate trusts you and this is how you treat him? You need to stop doing this to anyone. It's not right to invade someone's privacy like that.
It's cute to watch a guy taking a hot shower. I think he saw me and liked it.
Regardless of if you enjoy doing it, what you are doing is wrong. People expect to have privacy when they are showering, and you need to respect that. If you continue to spy on people, you will lose friends and could potentially end up with someone calling the cops on you.
