Wow, gan, I just read through the last few pages of your thread. What an interesting discussion. It's unfortunate that sex seems to be such a source of stress for so many couples when it has the potential to be so binding. I'm not going to weigh in on the topic, I missed that window of opportunity, but it did give me something to think about. And reinforces my belief that I settled for far too long but makes me fear that by refusing to settle next time I'll end up with nothing.
