I dont think you gave enough information about his behavior for me to give you an opinion. Narcissists can not love. They are blindly in love with themselves through their grandiose fantasies. They can not care about anyone but themselves and a true narcissist will not have friends. Narcissism is more common in men. A narcissistic man or sometimes women will see themselves as omnipotent, a "sex god" and will want people to hate them, fear them, admire them.. (also known as narcissistic supply: they want attention for the bad things they do, "players" "drug dealers") The great sex is not for you, its for them. They have to perform at the very best so they show themselves how good they are at it. Everything they do is for themselves, they may be very sexually confident but its really just selfishness.
