First thing, take a good look at yourself in the mirror and ask yourself if you're the kind of guy who will let himself get invited to go shopping for underwear with a female friend and spend the entire time acting like it's not a big deal and refusing to share the risqué comments running through your obscene little mind.
If you are, you're in the friend zone, but you walked most of the way yourself. If she has ended up thinking you're gay, that's pretty much on you as well.
Try saying what you're thinking. Either it'll save you from the friend zone or it'll save you a torturous afternoon sitting outside a dressing room while a woman you fancy tries on lingerie you'll never get to see.
