If you can tell me your favourite between Sam, Dean, Cas, or Crowley we will get along just fine.
Let's also make this clear. I am not into hook ups.
"Send a pic" is where I loose 90% of my interest.
Instant Turn offs: being called baby, the word tits, and tongue while kissing.
Dick pics. If I want to see a baby carrot, I'll go to the grocery section.
Negging: If I would be more attractive if I [insert improvement suggestion here], I suggest you move on. I often reply with my own suggestions for your improvement. They are made with a knife.
Starting any conversation with any reference to sex or being unable to have a conversation that isnt about sex. We're all fans of sex here, but let's, for once try to pretend that you're actually looking for a long-term relationship instead of a one-night-stand and subsequent attempts to avoid me.
Expectations of immediate replies to your messages: If you don't have a life to occupy you, try making one instead of playing emotional Invasion of the Body Snatchers.
Whininess: If you get upset because I'm not the person you are expecting to compensate for your faults, flaws, and inability to treat women like human beings in their own right, I immediately assume that you are incapable of arousing anything, including my interest.
