SRS review time
Regular Missionary - you're a depraved sex fiend, how do you even look at yourself in the mirror?
Advanced Missionary - too scared to go full missionary, basically the diet soda with calories (like Diet Dew iirc) of sexuality
Doggystyle - prosaic but timeless, just like your ancestors did when they raped and / or pillaged neighborhood villages
Cowgirl - you're lazy as fuck and too trusting of other people, likely hold a part-time minimum wage job
Sidefucking - you watch too much pornography marketed as being for women when it's really not (e.g. Passion-HD)
Reverse Cowgirl - same as cowgirl, but you can't stand to look the person you trust too much in the eyes, so you're lazy, have trust issues, and you're a coward
Side Hugging - an Evilbore conceit
Dry humping (GAFer option) - LDS or exotic dancer, possibly both
Fucking While Standing Up (all variations) - congratulations on having sexuality informed by Cinemax adult programming
Waiting For Virtual Reality Before Deciding (Wizard option) - you laugh but do you think EVE Valkyrie is going to move Oculus Rifts
