When you get to be a certain age, you know what you want and what you don't. You realize life is short. Time and energy are at a premium. Some of us choose not to waste time dating a person we know we won't enjoy. Someone else might take my list and call it a turn on list. I know what I can live with. I stick with that.
In recent years, I have turned down 100 % of men who have asked me out. At this point in life, I have no burning need for a partner. I'm past childbearing years. I don't see marriage as a must have. I would love to have an interesting love in my life, don't get me wrong, but I am not so desperate for it that I will waste my time with men I know could never be that for me. I'll give a man a chance, though, even if he initially doesn't seem attractive to me, to get to know me in a non dating way. I won't write off a guy for petty reasons. I stay single, just as much, because I don't feel I'd be the best partner for someone right now. For the right guy though, I'd give him my time and attention if he wooed me properly.
