I've always gone out with much younger guys. But I rushed into relationships before really getting to know the person. What would come up as a warning sign within the first two weeks of dating would usually be the exact reason the relationship would end!
I am very puzzled by the fact that young people are getting infected again. They don't take precautions despite an enormous amount of information. It's like riding a race car at 200 kilometers an hour. Some people like the risk.
