Hmmm ... I find this to be an interesting topic. 
There is a BIG difference between a woman who sucks your dick b/c she 1) likes you, 2) sucks your dick b/c she knows you like it, and 3) sucks dick b/c SHE likes it. All 3 of those scenarios will result in a different type of dick suckery experience for us men. And we can tell RIGHT AWAY ladies - so there is no faking. If you are a prude and thinking "well, he likes it so I GUESS I'll suck it" then for real - just stop it. You're the bitch that gets cheated on w/ some1 uglier than you and don't know why - LOL. Stop bein a pussy and embrace the suckery. LOL. 
 So... w/ that said - I am good at eatin' the puss... HOWEVER it is directly proportional to my interest in the young specimen before me. If I am feelin you FA SHO - oh yeah, I'll bring out all the stops - and if we are sexually compatiable then same goes. If the attraction is only so-so, it's not gonna happen - if I know 5 people that you have played w/ personally - not gonna happen - etc.
So while I can't say that I "enjoy" eating pussy. I do enjoy driving certain women crazy w/ pussy-eating antics... if that makes sense. That's the short way of saying, it depends on who the woman is and my interest in her. So the BEST answer for me is number 1, although that is subject to my desire for, relationship with, and/or interest in the lady.
