I been with my husband for six years and our sex life has not been so great. From June 2012 till today February 2014 we have sex 4 times and lately my sex drive has been wow that I have to masterbate twice a day. I do not know what to so does anyone have advice?

Why is husband not having sex ? How old is he, Is there medical issues ?

Have he or you been to doctor.

There's nothing wrong with masturbating twice a day, but any lack of loving between two people needs to be talked about with each other. Plan a time when you can talk to him about what you are missing (warmth of touch, stroking, and actual intercourse) in a calm way, and ask if there is anything going on in his life that is having an effect on his feelings. Don't complain or accuse, which isn't always easy, so think carefully about how you are going to say this in a nice way.
There are many reasons men lose interest in sex with their wives. Here are a few.
The number one reason is worry over work and money, and a feeling that the spouse is lacking in understanding.
Others in no particular order are such things as once a woman has children, she isn't seen as a sexual person by her husband. A wife becomes more like his mother. He has low testosterone. He is homosexual. He is having an affair. He is seeing prostitutes. He prefers masturbating, often to porn on the internet.
