Similar to an experience Your Professor revealed on the show! From Reddit:
I met my wife 7 years ago, she was extremely picky when it came to sex. She told me she only has been with 1 other guy before. She would never give a blow job, only would do certain positions and found almost every sex act degrading. I was frustrated by this, but I really liked her and hoped over the years she would open up sexually. Over the years, it never got any better but I learned to get over it. Well I ended up finding an old video from her college days of her engaging in group sex with 6 other people…
