Female libido is much more than taking a magic pill.
Can be related to hormonal imbalance, low self-esteem, obesity, side effect of the contraceptive, age, pre menopause, relationship... man... the list can go on and on.
Can she get excited? Or no... Never?
Does she masturbate and have orgasms by herself?
Have you try spice a little the sex... with toys, fantasies and even porn? More oral sex, hot massages?
