When a man has good intentions toward an attractive woman, has the best in mind for her, wants to honor her, and respects himself, and has the best of intentions for himself, he has nothing to fear from an attractive woman because he is trustworthy in his own eyes, and if the woman rejects him too bad it's not him, he's doing his best, it's just her particular taste.
When a man trusts himself to take care of an attractive woman he has nothing to fear from that woman. Note I did not say trust the woman. When approaching a woman for the first time, trusting her won't do anything, because you've got nothing to base it on, trusting yourself to handle all of what proceeds does matter.
Besides I don't think men really fear woman's rejection, ie it's not what the woman does that they fear...it's that they fear the woman will discover their ill intentions and uncover who the man really is. Besides if the man knows he has put in the work and effort honestly to deserve a certain woman(but it's up to her too, note), then he trusts himself enough in order to do what is necessary to honestly win the woman.
In other words I think us men need our brains and hearts to catch up with our other overdeveloped desires and become whole men, in order to present ourselves with integrity, and matter-of-factly without flinching, because perfect(whole) love, love with integrity, casts out all fear. Besides if you mean no harm what have you to fear.
