The sexiest (in no order):
ISTP, ENFJ, INFJ, INFP, ESTP
-ISTPs tend to be physically attractive, and their sense of adventure is sexy.
-ESTPs are terribly charming & fun.
-ENFJs provide that soul-mate connection and are incredily sweet and encouraging. They grow on you (not always sexy right out of the box).
-INFJs are like me turned inside out, and my insides are quite sexy, if I do say so myself.
-INFPs are unfailingly sexy, because we have the mystery, the INFP eyes, and because I am one.
This doesn't mean the other types are not attractive! You are all sexy to me
