She doesn't like sex

Please I seriously need advice on this. I'm in a stage of confusion now. I pasted a post here some time ago, and some of us here advises me to go ahead and marry the woman that she is going to be the best wife. I took to the advice, but now the woes is happening. Posted here that a girl I wanted to marry doest not like sex and we were in a serious relationship, and when I confronted her about it she told me I should marry her first before sex. Recently we have started the marriage process. I have done the formal introduction which causes some good amount of money. And I also pay in some money in cash as been demanded by the family, and we have finished every arrangement on the payment of the remaining things but I have just relies that my wife does not like sex. To the extent that she told me I should go and get it somewhere else. Her complain now is that I stay too long on sex. We hardly have sex ones in a week, but she always one me to stay around her. I can say is always on a serious pressure that we can have sex two to three times in a month. We can be together in a house for one full week none of us goes out but know touching. She is no longer a girl. We are of the same age. I have not been satisfy in bed with her. Now the issue is how long will it continue and I is it true that I will have two wives? Or I should not not continue with the remaining process which is to pay the remaining things including the Britt price? Are this things are what I'm thinking. Pls I need advice.
