I (22GF) am Asexual and in a relationship with my partner (21F) who is hypersexual, both from a place of trauma and sexual enjoyment. She's never pressured me for sexual things, and we've been working towards what I'd be comfortable with sexually and discussing whether Ethical Non-Monogamy, specifically the ability to sleep with other people, would be positive for her--she thinks it will be but recognizes I'm not in a place to handle that right now emotionally. I'm really worried that I'm going to agree to something that enables a trauma response instead of an actual desire or that I'm not going to be enough in some way.

The latter is very heavily caused by the fact that my partner sees herself as a danger to me sexually. She thinks she's going to do something bad to me if we interact sexually and is therefore having trouble seeing me as an acceptable sexual option/consenting sexual partner despite being attracted to me and having my verbal reassurance. This has led to insecurity and (for the first time in my life since this is also the first time I'm experiencing any sort of sex drive) slight sexual frustration on my part. Her fears and negative thoughts around herself as a sexual being are also feeding into my concern that I'm going to miss a sign that something is a trauma response.

Do any of you have advice on how best to support a hypersexual partner?
