Myself and my other half have been together for a few years, at the start of our relationship our sex life was great! I couldn't ask for better!
But ever since I had our son, my libido has just gone, and I don't know why. I have read a lot of articles explaining that your sex drive does go after having a baby... But our son is a toddler now! So shouldn't my libido have come back by now?
And because it hasn't why?

This is putting so much strain on our relationship!

Could anybody give me some advice to get our sex life back?

Yes, your libido goes down after having children. True story. However, there may be some hormonal changes that have not corrected themselves since the birth of your child. Time to talk candidly with you GYN as well as your partner.

Sorry to ask this, but I have not heard of Candidly or GYN.

Candidly means talking to your doctor and your partner about exactly what is going on.

GYN = gynecologist.
