obviously that isn't a bad thing on its own, but doing it every time points to a flaw in your own masculinity and lower masculinity is associated with gay men who are expected to act more feminine.
this is also done while dressing yourself up to look like a frankenstein of a gay man, a furry and a e-thot. which are tend to be more feminine.
