While it's very true that women are no longer the natural subordinates in relationships, a man with leadership skills is still very attractive. Nobody wants to be in control at all times, so it's great to be able to rely on your partner to take charge in certain situations. Some couples like to divide the shared duties, while others will take turns. Either way, the ability to step up will really improve your chances with the ladies.
If you feel like it's always your partner who is running the show, ask her if she'd like you to handle some of the duties. She'll most likely appreciate you taking control and being willing to lead. Don't sit around waiting to be delegated to or you could be damaging your relationship or causing your partner to be less attracted to you.
