Carer took pictures of my penis

So I’m in a weird situation I’d like some advice on.

I’m disabled and have carers in. While getting dressed after a shower my carer took a picture while she was holding my semi hard penis. It was slightly aroused for multiple reasons (part of how my spinal injury, the way she was drying me etc)

Anyway I questioned it and she said she wanted a record of a red mark near the base. I’ve had other things pictured in the past just not intimate areas.

After I was dressed I by chance noticed that she sent the picture in a message to contact called ❤️hubby❤️

I didn’t say anything at the time and not sure I’m I’m going to because of all the stress that will come of it. Just want to know where the line is with SA?

I fully think it’s a sexual thing for those two as the way she was gripping with her whole hand seemed off thinking about it afterwards.
