So inquiring minds want to know....why do 3s end up divorced? I have my own suspicions but wonder why the OP threw that one in there? Lol
Imho, 1s are the long term SOs, 2s are the girl friends or SOs of five years or less, 3s can be any and all of the above who for some reason or another one day just said "fcuk it, I'm gonna start getting paid for giving out shit this good" and here they are.
If you aren't a 3 then you probably need to find a new line of work. Gag reflex, swallow or not, doesn't mean you love it any less. It's like saying a guy with ED doesn't love pussy as much as an eighteen yr old jackrabbit - it just ain't so.
