I (29M) just want some general advice on what to avoid saying to someone that I find attractive. I'm mentioning the "attractive" part because I do tend to notice people that I find attractive, but I do struggle with an insecurity of feeling like I shouldn't talk to someone just because I find them attractive. At the same time I do get the urge to go up to someone and tell them that they look nice, even if it doesn't lead anywhere.
I'm not sure if there's any proper etiquette I should be following, but if anyone has any feedback I'd greatly appreciate it.
