Advice needed from wife’s

I understand my husband’s reasoning for wanting to share me. He’s very much about compersion, and I do feel something similar in some ways. I’m incredibly grateful that he’s comfortable with me exploring this side of myself and we have so much fun doing so.

At the same time, I struggle with the idea of him being with another woman. I wish I could fully reciprocate in that way and be comfortable with it, but I’m not sure I can bring myself to give him the go ahead. I feel torn because I want things to feel equal, yet I can’t ignore how it makes me feel.

Are there any other women who feel the same way?
