Actually it's the trans-ideology I can thank for making me realise quite how 'penis centric sex' is considered the only way.
I was watching a video of a woman who went round asking men when was the last time they had sex. They answered, various answers. She asked whether the woman had had an orgasm. Almost to a man, the answers were I think so, I'm not sure, um maybe, or just plain no.
She then asked, in that case, how did they know when the sex was over. Again, to a man, they said after I had an orgasm.
And yes, the outraged whining that if a lesbian uses a dildo, then she should be fine with a penis. The absolute blind incomprehension that sex may not be PIV, is staggering.
Particularly in light of the fact that a woman's orgasm is centred on her clitoris. Which, is generally, a hit and miss affair during PIV.
Come to think of it, even the word foreplay reflects it, as though pleasing a woman is merely a warmup for the main event.
