I think it’s refreshing that you have a “this is who I am” approach and ask that others respect that, rather than trying to be rigid about putting yourself in a box. Human sexuality/romantic attraction and relationships in general are complex, trauma or no, even though some people might try and convince us otherwise.
For what it’s worth, while I’m not an ACE (but am a trauma survivor) I have still suffered micro aggressions because I have a low sex drive, and I’m very rarely seen hanging out with people who aren’t other women - I am straight, just not that interested! I think the micro aggressions come from others feeling like they’re entitled to other people’s bodies in case they want sex - the base message I hear (and I’m not sure if you feel similarly?) is while I’m not obsessed with getting laid, if they want it I should be ‘available’ regardless of my own feelings. It confuses and offends them that I’d rather not participate.
