I'm a straight cis female. One of my best friends is a lesbian who rates about a 15/10 on the "10 is so gay it hurts" meter. If you put both of us into an Exodus session - which for females includes training in applying makeup, fixing hair, cooking, volunteering for blowjob training... (OK, I made that last one up) - she'd go straight to the Advanced class & I'd be stuck in the "wearing lipstick is part of being straight" remedial class. It's all bullshit.
