Like, I really only wear t-shirts and jeans, I own a single dress. I share the same humor and interests as my guy friends, and most of my friends are guys, I am straight, but I have been asked before if I was gay because that guy that had asked had "never bantered so well with a straight girl". Haha, kind of assume most guys just consider me a friend.
Not necessarily. There can be unattractive tomboys and there can be attractive ones. I love them personally. They are not so delicate and can play a little more rough. They're often into the same stuff you are. They're cool. Don't be put off by the guy asking if you are lesbian. As you grow older, the world around you gets more nuanced. He just learned one more shade of gray. That not all tomboys are lesbians.
You sound attractive to me I really hate fashion and literally have 3 pairs of jeans, some shorts and a few tops and I really don't want to talk about it so someone who also didn't care would be cool. I really don't care for very feminine girls tbh.
Generally (but not always) guys will be turned off if there is nothing feminine about you, but femininity can come in many different forms: you can appreciate crude humor and not wear dresses but still be feminine in some other way.
if they are physically beautiful, sweet and have good morals, than yes they are attractive, but if they have tattoos and piercings all over and trashy, smoke, drink, do drugs, have casual sex partners, even with girls, than yes they are really unattractive, and wouldn't want anything to do with her.
