Wolf, I have to disagree. Except the bit about changing the rules.
I wash at least daily, groom myself fairly well, dress decently (usually) and am willing to commit to a LTR. I like to think I'm socially presentable. I can deal with the hormone thing for the most part. True, I am a prevert. But I'm a *nice* prevert.
That said, My relationships never seem to last very long, six months is average. One year is a record. And it's always "my fault". I normally fail to see what I might have done wrong. Sometimes I do see it and strive to not do that thing ever again. I look at this as a positive thing. Women seem to disagree.
There HAS to be more to it than simple grooming and staying faithful. What aren't you telling us?
