Not sure tbh, but the people whom you're describing definitely exist.
Makes you wonder, after some subhumans have no luck with Tinder, they go on Grindr instead? I think it's obvious that you can condition yourself to be more attracted to certain things through exposure, that's exactly what I did with 2D. Seems like a bad cope through, I find the thought of doing anything sexual with other men to be repulsive. For a man with the same purely heterosexual inclination, conditioning would only get you so far. If anything, I think this sheds light on bisexuals potentially just being copelords.
