I was wondering if you performed with multiple partners or just the two of you, as this may make a difference to some people. For me, I don't know that I could handle multiple partner on-camera sex. However, a couple who performs as a couple wouldn't hinder me at all. (But I am married so not a unicorn.
If you do have multiple partners, or know other women in the industry, you may have already met someone open to what you desire in your own line of work. If she is already alright with the sexual aspect (which I found the most difficult and am still trying to get over), and has the ability to be emotionally poly, she may be right under your *ehem* noses.
I like to think there's someone(s) out there for everyone. So welcome, and happy hunting.
