Lofinger - a guy who secretly wants a finger up his ass when having sex but will never admit it.
Nofinger - a guy who will bitch slap the kink out ya if you try to slip a finger up his ass during sex (aka closeted bi-curious)
Profinger - A guy who likes a finger up his ass when having sex.
I hooked up with John again last night. I'm still trying to figure out if he's Lofinger or Nofinger. Maybe I should just go for it...
