Both can be harassment. Shocking I know but, touching a guy without his consent is harassment, just as it would be to a woman.

Also our chest/nipple region[atleast for me] is a very sexually sensitive region and whenever It's touched even I feel discomfort so it's not only females due to their breasts.
