Is it normal to worry about this?

Sometimes I worry that a straight girl will think I am hitting on her when I am actually just trying to be friendly.

I have a friend who might be straight and sometimes I worry that she will think I am hitting on her. :( that would be really awkward if she thought that. But if she isnt straight and I find out, I think I will stop worrying about this.

I don't worry about this kind of thing if the girl is gay or bisexual. Just straight girls.

I dont worry about it with guys either.
