When the wnbr first started in 2004 in my hometown of vancouver the first couple of years most of the women were militant about people not taking their photos. People with cameras reminded them that it is legal (in canada) to take pictures of people in public. Most of these women did not ride again. One year two guys and a gal left the pre-ride complaining about the photographers and i yelled -good riddance we do not need you anyway. I mean (and this has been remarked on this site before) --u are naked in public what the hell do you expect.
My suggestion would be to just get naked and they will loosen up---also you might just find it very fun. Vancouver does not get many repeat women but from the rides I have been to (which is 14 out of 18 rides) most women on the ride were ok with being photographed with the odd exception.
We did have one ride though where a person with mental problems was trying to smash peoples cameras at the pre-ride body painting--but the police took care of him. Actually (sorry to ramble) it was kind of funny in some of the earliest rides there was one or two women that would complain to the police with the expectation that people taking pictures would be arrested. They were in for a rude surprise
