Sending a photo...

It is a thoughtful gesture, and it's always nice to put a face to a name. I always welcome photos (tasteful, of course), though as Sweet N Little said, I certainly understand why most gentlemen opt not to.
I think that it is a very sweet gesture, but for me, I enjoy the excitment of not knowing until the door opens....
I have never been asked to send a photo, but do so as a courtesy. And it's always fully clothed. I wouldn't think of sending anything tasteless.
