I agree with you somewhat machiavelli. Though I think your statement 'Actually, I didn't need a study to tell me this - I lived it for over twenty years.' says a lot. I wonder, due to having read many of your posts, if maybe you have swung too far the other way. And taken on too much of the 'man' qualities and left all others behind. Like is said so many times, life is about balance. I hope you have balance in your bloke-ishness.
I agree a man maid is not attractive. Not if he does all and the woman does nothing. I also think that a stay at home dad, if the wife is out doing all the earning, this does have some effect on the way he is perceived by his wife. Even if only small. Though if it is done through necessity, for a short period of a few years as a means to an end, while the children are small, I don't see that it has to have any effect at all on the marriage. It is practicality and necessity only. And that is fine.
I think a doormat in any situation, male or female, is wholly unattractive.
I think the best attraction is when there is a team. Solid and helpful and caring. That creates lots of love, and not just the emotional sense. I have had all 3 types, though the man who did not lift a finger to help, he also didn't do the 'men's' jobs either. I did all. He was just a lazy fuc*er. So, I do also think it depends on the personalities too.
My man, he helps me in all I do. We cook together, we clean up together, if I cook he washes up. If I am hanging washing on the line, he helps. If he sees the floor needs hoovering, he will do it. We both work. He full time, me part time. It is about spending time together and helping each other in whatever needs doing. And we get along famously. The attraction is passionate, and I have never felt so perfect with another man as I do him. The fact he helps me does not put me off him. Not one bit. Quite the opposite in fact. It makes me love him more. And if I love him more, I want to have sex with him more. All the time in fact.
