Any religious argument against LGBT folks works just as well on Ace folks. (Which is to say they don’t, but the people making the arguments think they do)
Back seat of a car at a green space/park, but it didn’t get very far, so I’d hesitate to really call it sex. I’m pretty much ace though, so that’s the best you get.
Counterpoint: I didn’t discover I was trans until after the wrong puberty made being trans a lot harder. Going back to before that would let me right a pretty grand sense of wrongness.
