Just let the 'old folk' get used to it. I've been through that 'asian' debate.
By the way, Douglas has had probably the same feelings when shooting Marilyn. That was also his first boudoir shoot.
Only advice I learned, never ever tell anything about the shoot!!! Keep those moments private forever.

I wouldn't be so fast to introduce it into my wedding website. I'd test it apart from that first to gauge reaction.

So it's going to have to do with what the societal mores in your market area area.
