I will agree that there is one big difference between a male being harassed and a female being harassed. Most men are bigger and stronger than women, that is just the biology works. So when a man gets harassed, he can defend himself because he is stronger, most of the time. But when a woman gets harassed, most of the time she can not.
Yikes, this is exactly why there is a stigma around it. Because for a man to admit it, he will believe that others will see him as weak, as your post proves.
