There are several issues in what you are saying.
1. Men, when facing harassment, assaults, domestic violence, are usually not taken seriously either, especially in subcontinent. People act like the man 'must have wanted it' and if he doesn't, then he's either weak or gay or some other BS like that.
2. Because of that, far more violence on men goes unreported.
3. If women report something happening to them to a group of white knights, those white knights will beat the living pulp out of the alleged perpetrator. The same cannot be said the other way around.
4. Issues of groping and molestation especially will not be 'very insignificant' especially if a proper study is done about this problem. Because of the fact that no study exists, most of us just fall back to our intuition, which tells us it is almost impossible for men to be victims. But the same logic is used by uneducated people about domestic violence. And then look at domestic violence studies, that show that in nations (including "misogynistic" ones like Iran) where proper studies have been conducted, domestic violence is roughly equally perpetrated by men and women:
