To your chosen headline:
Usually a man only gives effort to please a woman if she is worth it or you like her really much. Only then a man has thoughts during interaction to please her.
Otherwise you just look for your own pleasure.
Only your self counts in such thinking. You anyway please the woman with your physical presence, if you like her, you give her the bonus.
P.S: That sounded a bit macho. But this way it function at least for me.
