Hmmm. Only Experience. Once upon a time women often believed that men married because of .... well, intercourse. Nowadays marriage isn't much of a necessity for most people. I've said, for years, that many men marry to have someone to do all the sh*t that they don't want to do. My husband is much better than most (and, believe me, I took a few for trial runs), but even so, he truly does not know how to run the clothes washer. He doesn't know how to do keep-up house work -- he's great at what we call "the white tornado", that is to say really cleaning before a party or having guests. But to look at something that's a bit of a mess and just pick it up? Not gonna happen.
