I am 57 years old, my partner is 47 good in shape, and enjoyed sex over 27 years. But now-a-days she is not much interested in sex .As a result my libido also redused and lost attraction in her body which is still in some what good shape.it takes three to four days to get next errection with her, but with any other lady my errection is quick and I can repeat it daily! What could be the reason and how can I bring her libido back

Has she spoken with her doctor about it?

Menopause can REALLY mess with your hormones, throwing your libido really out of whack.

I suggest she start with a complete physical, and talk to her doctor about it.

I suggest that after 27 years sex can become repetitive and familiar.

Also, as women get close to 50 their capacity to respond to sexual stimulation can really change - libido can decrease as the hormones change and what was previously enjoyable becomes annoying.

It's a difficult phase to navigate and it takes patience and creativity. The libido often does not come back as strong, and it requires both partners to think about sex differently.

Talking about it is a good first step. Getting her hormones checked is a good second step. Acceptance that your sexual relationship changes as you get older is a great third step.

As an aside, who are these other ladies that you get erections on a daily basis with?
