Going to an Indian restaurant and asking for a lot of spice can work… if you’re a veteran of Thai or Mexican spice first

Absolutely, there’s a lot more to it than just the genitals, but to be fair, everyone has a large number of differences from the mean- I’ve met bio women with very deep voices, with unflattering figures, who’ve experienced misogyny, etc.

Apart from the genitals, everything a trans person had that might differentiate them from a cis person can still be present in a cis person.

Yes. Penis or vagina matters little to me.
