what's the most romantic thing you've done for a girl?

Understand that this applies even to non-sexual situations. Women are more likely to be asked for favors from coworkers. Regular “can you file this for me” / “can you cover my shift” / “can you finish up this paperwork” workplace favors. Men are less likely to return those favors. Women are more likely to be seen as “difficult to work with” if they refuse to do favors when requested. Being viewed as ungenerous has negative social and professional consequences.

All men benefit from women’s reinforced fear of being hurt for saying no.
