No. However, if she was uber-rich I wouldn't be opposed to having a sugar Momma and playing that into dynamic for free rent and lifestyle upgrade, but I wouldn't take her or the relationship seriously.
I actually had an opportunity for something like this a while back. I met this girl who worked in finance, i think she was a hedge fund manager or something and made a LOT of money. She said she was about to move out to CA and wanted to find a guy to move in with her and was 100% okay with being the breadwinner....but I couldn't help myself and told her that it was unnatural for a man to be in such a position.... and so nothing came of it. In hindsight I think I should have given it a try and felt like an idiot for fumbling that. I am not a hard worker and i'm not totally unwilling to degrade myself for money....you get free rent and lifestyle upgrade and regular sex, whats the issue? If the relationship turns sour, just leave. The benefit here is that since the place is in her name, you have the freedom to get up and leave, which actually gives you a lot of power. For this reason if you are going to cohabitat with a woman (which I don't think a man should ever do), it actually makes more sense if she's the breadwinner since she is the one with something to lose.
Anyway...in the context of an ordinary LTR and ordinary circumstances, I would never do that in a million years.
