I'm 37 and I'm having trouble mainting an erection during sex and my wife is not being kind in anyway. We have three kids and it's hard to get some alone time. So when there is sex it's always very fast no foreplay no nothing . She gets her fix I get mine. Now for the past three months I have not pleased her in anyway. Shes a very controlling person . Or most recent sexual encounter was her manually stroking me I kept telling her that I wanted to make her cum first . I know she likes to watch me cum. But then she wants to jump right on top of me and have sex and it takes time to recharge and get hard. I feel like I'm worthless I've always been a sexual person. Always have to chase her for sex. And every since my problem started. She has become very sexual. I feel she got in my head. I smoke pot and drink on the weekends sort of exercise. Looking for any advice. Thanks
