I hope you can give me advice. The mother of my son has changed towards me ever since we had our son. She doesn't enjoy sex with me like she did before.

I hope you can give me advice. The mother of my son has changed towards me ever since we had our son. She doesn't enjoy sex with me like she did before.

I have confronted her about this and we tried for about two months. Just when I thought it was all back to normal, she told me she thinks our relationship is based on sex.

She stays at her parents' house and only spends time with me on weekends. We have sex only on weekends.

So for me it has come to the point where she doesn't want to have sex with me, but I don't want to look for sex outside our relationship.

You are a selfish man, aren't you? Has it ever crossed your mind that your girlfriend's body has gone through changes after being pregnant for nine months and then giving birth? Have you for one second thought about whether you would be feeling sexy after going through this?

Men like you make me sick. All you do is whinge about your problems without once considering what she is going through.

Is she breast-feeding? Is she up most of the night every night with the baby? Is she getting enough sleep? Does she have a moment to herself in a 24-hour day, without you or the baby demanding her attention?

Grow up and learn to behave like a man, not like a randy teenager.
