Would we call fondling male breasts (a "nipple twister" the internet informs me is called) or a slap on their ass (butt slapping, common sometimes after a sport game) against their owner’s will, a sexual assault (much less rape)? What if it had been performed by a stronger man to another weaker man, but in some casual setting?
How serious would we consider it, and how "traumatized" we would consider the person after the incident? (Some would call it "very serious". But then again there are people who suffer trauma over a wrong order at Starbucks).
At best most people would call it a tasteless antic or light bullying or crappy behavior (like farting in public)...
A better example is "tapping": a quick backhand to a male's crotch, trying to hit the testicles hard enough to hurt but not hard enough to incapacitate. Riot Games' COO, Scott Gelb, got two months of unpaid leave after he "repeatedly touched subordinates’ balls or butt or farted in their faces" [0].
I would absolutely describe that as sexual assault; deliberately, just to emphasize that playful male aggression crosses lines that absolutely should not be crossed, including in the workplace. Touch my balls without my consent, and I won't care whether you're horsing around or making an awkward pass. It's assault, and it's sexual. It doesn't cheapen other kinds of sexual assault to draw clear boundaries.
