I don’t understand how the way you dress can be considered as ‘gay’.. Being gay is a lifestyle choice, not a term used to describe something negative; so no, I don’t think wearing skinny jeans makes you seem gay or non-masculine.
I think skinny jeans are perfectly fine for an everyday look, however, for more formal occasions, I prefer slim fit trousers. I guess the only problem I’d have with skinny jeans is if their too tight.. like almost looking like leggings.
But if you like to wear skinny jeans or whatever, then do it, fashion is a personal thing, wear what you want.
