I'm new, making my way through the sidebar. I'm finding limited information about certain concepts I don't fully grasp. I'd appreciate some clarity on the gatekeepers concept.

I understand women as the gatekeepers of sex. I partially understand men as the gatekeepers of commitment.

How are men solely the gatekeepers of commitment, does this not require action on her part as well? Is this in direct relation, she removes sex you remove commitment?

Along the same lines, I often read "It's her job to maintain the relationship". Can someone elaborate on this concept. How does this translate into action on her part? From the perspective of a guy that has successfully achieved his MAP, what does her maintaining the relationship mean?
