selling nudes

Hollie • 19 • feminist • college student
For the past year or so I've been selling nude photos/videos to strangers on the Internet. I'm a broke college student with a part time job, so money is very tight. 
When my partner and I made our relationship official, I told him that I sell pictures sometimes and he got really angry with me. We got into an argument over it because I believe women can do whatever they want with their bodies, especially if money is in the situation. Eventually, he apologized for getting angry and said he understood where I was coming from. 
For his comfort, I now only sell photos of myself, keeping the sexy videos for my partner only. 
Does anyone else do this? How do you keep your identity safe? How have the people in your life reacted?
