Still haven't figured out why girls don't mind running around in a bikini, but those same girls freak out if a guy sees their bra and underwear. What's the difference?

Well, it depends on the context mostly.
If I'm suntanning at the beach then wearing a bikini is perfectly acceptable.
I wouldn't feel weird about it because we're at the beach and that's what people wear in that context.
But if I was getting changed in my room and a male person happened to see me in my underwear then I'd feel funny and get embarassed. That's mostly because it was a mistake, it shouldn't have happened, and the context wasn't right.
Also, just in my own personal experience, as I'm quite shy you won't see me "running around in a bikini" because I feel there's not enough coverage / fabric for me to run around carelessly. And it might take me a little bit of time in order to get adjusted to the sense of nakedness that wearing a bikini entails. Some girls are like that, you know.
Hope what I wrote makes sense! :-)
