Just thinking about this, I think a lot of these questions (including the Nice Guy thread which I can't be bothered looking for the url of) , I think a lot of these questions can be resolved by one thing: balance.
You need to balance all these things out. It *is* nice when your gf takes control once in a while. Doesn't make you any less male. So long as it's not *every* time. And as for being a Nice Guy? Well, lets just say your gf's father passes away. What are you gonna do, be an ass? Damn right you're not.
And remember that a lot of posters here are good DJs but haven't been in too many LTRs, and may be relatively young (me included in both of those btw). I'm not raggin on anyone but it's good to balance shit out. So take all these things with a grain of salt.
