As for balding and obese... mmm not sure I want to go there because I don't judge anyone on looks. I will say that photographers I've met and worked with have been all over the spectrum of attractiveness. It was never really an issue. A photog is either good or not... looks don't really matter. You aren't there for the hookup. I'm not getting how that's a problem. You think you might be more comfortable working with a woman?
The other thing... yeah that could be iffy. Not because he's BP of course because I'm guessing you are too
But it could complicate your work with the support group. I don't see anything creepy about him either. I guess I'm missing that paranoia gene. I've seen the two pics you showed me of you in the bathtub (non nude or even suggestive in case anyone is wondering) and I wouldn't have recognized you after seeing a normal (for you :P) photo. I think you'll figure out what's best. You don't seem like a person who would get into a compromising position. The photos are yours right? You can have them downloaded straight to a flash drive or something and watch him delete the camera files.
Oh and yeah that was quite a coincidence wasn't it?
