I am very frustrated. I have never really been interested in sex. I was only interested in it with one boyfriend who turned out to be a real jerk. I didn't want to have sex with him after awhile. I thought I was crazy but I am 29 now and all I can think about is sex. I do not like casual sex and I am not in a relationship nor do I want one but I'm always in the mood. I don't understand, this feeling came on all of a sudden. I also read many articles saying, "a woman's sexual peak is just a myth". Has anyone experienced a sudden increase in sexual desire for no reason?
