I think if you can handle an unbalanced relationship (and actively want it) then it can certainly work, but only if both parties are of that mindset, which is probably where the difficulty lies. Finding someone you're compatible with is tricky enough, but finding someone you're compatible with who shares a relatively unusual perspective on relationships makes it all the more so. People with more traditional requirements can focus on other things like whether their taste in bands or carpets match up, whereas those with more complex (and yet, simple, in their own way) relationship requirements have to make satisfying those the first step. And they should, if that's what they want, because settling for something that goes against your desires is never going to work out.
(Incidentally, I have never found a salesperson who can sell me anything I don't already want. Hmm!)
It's interesting looking into other relationships and seeing how other people tolerate and actively pursue things that would make me run for the hills (or just wallow in worsening mental illness, most likely). I know quite a few acquaintances in relationships which are really skewed towards the traditional 'man does everything, girl acts like useless fawn' type and they bring me out in hives. I used to think I'd never be able to have a relationship at all because I'm so stand-offish in the real world and value my personal independence far more than I thought would be acceptable to another person. But nowadays, I live for mundane exchanges like this:
<Mr Rui> Hmm, we need to sort out the spare bed.
<Rui> Darling, I got some new pillowcases earlier this year which would be perfect.
<Mr Rui> Where are they?
<Rui> In the Play-Asia box.
<Mr Rui> Ok... *gets them out and starts laughing*
<Rui>
<Mr Rui> I suppose I should have been suspicious from the box.
(We now have inoffensive BL-decorated pillowcases. It feels bizarre that I'm a grown up and I can still do things like this.)
I think what I'm trying to say is that I really like being myself and being accepted for that without having to pretend I'm something else or follow the rules. Rules suck (unless they're there to prevent people hurting one another, I guess). We're probably all weirdos to some degree or another, being on an anime forum and all, but there are a lot more weirdos out there than people like us to think.
