Still not disagreeing with you, as, since humanity evolved upright posture and some self-awareness, additional tricks of biology have evolved alongside primary function to promote sexual reproduction. Nipples also demonstrate arousal and the mechanical manipulation of them and their sensitivity around certain stages of the menstrual cycle provided clues to early man about ovulation cycles that were no longer outwardly demonstrated as had been for all of humanity's precursors.
So, yes, lots of functions of the nipple, many evolved. Sexual pleasure, however, is a dead last because that is about the last trick needed to get humans to reproduce. (It comes along when higher brain function does, and that is the last thing to separate us from apes.)
