My first bit of advice -- women aren't men! Okay, so it seems as if I'm stating the obvious, but I'm not. Our center of gravity is different, and as a result, bouyancy is different.
In the first OW course I took the BC and weight distribution guaranteed that at the surface I had to fight to keep my face out of the water. It was miserable. I thought it was something I was doing wrong, and didn't realise a couple of simple adjustments to my gear would make diving a more pleasant experience. (Trying not to drown while listening to instructions is distracting and stressful.)
If the instructor or DM realised what the problem was, they did nothing to fix it. (Interestingly, not one of the women who started the course finished it.)
When I changed shops, the DM tentatively explained why things weren't working out. He was a little uncomfortable talking about female weight distribution -- I think he thought I would be insulted. But we moved the weight around and experimented a little, and I switched from a "unisex" BC to one meant for women. What a difference!
As for the groping thread -- my brother is a rifle coach. Before he touches a student, male or female, he explains what he is doing and asks permission. It's meant to avoid any misunderstandings or discomfort. If it's a matter or safety, or you're underwater, you may not be able to comment then, but you could explain in advance that some contact might be necessary.
Good luck!
