There is no way to say this without sounding overly arrogant but i have discovered that most men do a lousy job pleasuring women.  I have been told by several that i am the best they ever had.  This is because i pay attention to the woman.  If im doing things right then the woman will orgasm at least once before i even penetrate her with my cock.  This is possible due to being open and talking freely about sex and pleasure,  along with noticing changes in the woman.
