"I’m 30 and my wife is 29. We are Nigerian and have a boy of 12 months.  We do have sex but I have to take Viagra to manage it. I just don’t feel the urge these days."

Don’t self-prescribe Viagra when the real problem is almost certainly psychological. It sounds as though you just don’t feel ready for another baby yet.

Be honest with your wife. Say you want more time to enjoy your relationship, get used to family life and to give your little boy plenty of attention. He will benefit from that as having two children very close together can lead to the older one feeling pushed on one side too soon and lots of jealousy.

Once you start using contraception again, I think your sex drive will go back to normal. If you still have problems, my leaflet on Reviving A Man’s Sex Drive will help.
