the f-slur can't be reclaimed for me, personally, I'm happy for those who do reclaim it but its just too painful as it's what I got called when I was badly hurt and was worried I would die as a 12 year old.
However, those who do reclaim it then use it around me, which just makes me think about what happened - involuntarily - and ruins my day (or part of it).
It's also tricky being a bi man in a het relationship in this regard, as if someone knows that it's hard to overcome their feelings that due to my partners existence, I now no longer have a say in these matters.
