I don't know why my wife is suddenly not interested in sex anymore. We have been married for 7 years now. And we have 1 child and presently she is 6 months pregnant. I am very active sexually. From the beginning my wife too was very active and high interest in having sex. But I don't know what went wrong. Infact my wife seems not to indicate interest at all. Sh has turned me down severally. But I thought I know and I do all a man is suppose to do, ranging from fore play to giving her orgasm. I want my wife sex life to increase. The issue is that she doesn't see anything wrong if we stay without sex for one month for no genuine reason. And after such a long period, if I make demand for sex she still feels I am disturbing her. The question is does she need medical attention? I am getting frustrated. Please help. Thanks.
