Last year I went to a shoot with a lady who wanted some nude and erotic photos for her profile on a swinging site. We shot at her place. Things went very smoothly for a while and we were laughing and flirting a bit as she slowly disrobed.
But when she got down to her knickers she stopped. I asked her what was wrong and she said she wanted something to look at if she was to continue. I was a bit slow on the uptake until I saw her looking at my crotch. I asked if she was asking me to show my cock and she nodded.
Now I’ve sometimes in the past been uncomfortable with the optics of a clothed man photographer giving instructions to a naked women model. So I had no qualms about evening things up a bit.
So I stripped off completely and the shoot continued to a satisfactory conclusion.
