My husband is on blood pressure med, but sex don't seem to interest him as much as it does me. I use to worry him a lot about having sex, but now I really don't care if I get it from him because he can not get or keep a erection. What must I do. I am very flustrated. I have a vibrator, but would like him to be involve. He shows no interest. He does not try to do anything to keep himself fix for sex. I figure he really don't care about it or pleasing me sextually.
