Hi Looking,
Welcome to the forum! It's good to have you join the conversation.
Ugg! You've asked some tough questions. Not because the questions are hard in-and-of themselves, but because the answers I give might not be what you want to hear. And since you're new here, I REALLY want you to feel welcome and stick around to read and contribute. Honestly I do, so when I read you original post, I thought I should remain silent out of courtesy but hearing your plea for answers a second time, I feel compelled to reveal my thoughts and HOPE that you're not put off by them.
Regarding flexibility. I've never heard anyone claim increased flexibility as a benefit and I haven't experienced it myself so, IMHO I think it might be something else causing it for you. I'd GUESS, greater flexibility in women is more a factor of skeletal and muscular differences than hormones but I could be wrong. Regarding the emotional inquiries. Personally, I'm a little surprised (perhaps even skeptical) that you got an emotional response so quickly and honestly, I wonder if it's more of a placebo effect than anything but who am I to deny your experience? Sorry if that's not what you wanted to hear. I hope you appreciate the honesty though and don't take offense.
