First of all have a hug xxx the good thing about photography is it doesn't matter what size you, you are probably aren't as big as you think you are

and most men like curves
I started photography last year, and felt a right numpty fiddling with my camera outside, felt like everyone was watching what I was up to. Especially when I am at some weird angle ,or lying down trying to get the shot I want
TBH it doesn't bother me anymore, I just concentrate on the shot, I still have a fear of street photography, dying to try it, but bottle out.:shrug: Also, if I catch someone really staring, I just give them a smile, and usually they smile back, and even come and ask me what I am up to
