I won't go into detail about what happened, but every time I have sex with her, I feel deeply insecure. I worry about her well-being and it's at a point where I recognize that it's excessive. She's the type of person who has high libido and is proud of it, but it's increasingly hard to reciprocate those feelings — I feel like less of a partner because of it. Would telling her help? Would it deepen our relationship or drive us apart? I love her for who she is as a person, but I worry immensely for not satisfying this area of her needs. Feedback appreciated, thank you for reading.
