Got a close friend I've hung out with a ton in college. She's currently in an LDR with some guy back home, but we've had some real talk a few times and know quite a bit of each other's secrets. People already assume we're dating too. Is it weird that I asked her why she was acting so strange tonight and she responded with that she was really horny because of her menstrual cycle. When I said that that was a little weird, she responded with "well I figured you wouldn't care" and continued to make more sexual references, a couple including me.

Wat do? Is this just purely being truthful, or do I have something to be concerned about?
