Trauma may or may not relate to asexuality, it varies individually. Cases in point:

- My female ex partner (during the relationship) had various similar traumas which made her think she was asexual/demi at the beginning. Turns out that was not the case, as she healed over time suddenly her drive jumped up to standard allo level and stayed there.

- I am grey/demi & with similar traumas as well. Before those traumas I was sex-indifferent, and after the traumas I became sex-avoidant. And as I'm healing im very slowly drifting back to sex-indifferent. I was asexual both before & after the traumas, traumas only changed my attitude towards sex, not my (lack of) sexual attraction.

- One of my close friends is gay & was completely sex-repulsed (but never explicitly identified as asexual) for many years, but as shes finally healing she's opening up to the idea of physical intimacy with people.

Of course none of these stories may necessarily relate to yours, but my point is that there's no universal answer for the topic of trauma-asexuality interactions.
