Meh, just give up sex altogether. Nothing bad ever comes from that. Just look at Catholic vows of abstinence. Perfect example of best practices.

Its getting so bad men will give up women all together.

This will give rise to a new meaning of MEN's support Group.

Circle jerk.

The next time a girl looks at my crotch bulge on the bus, I'm gonna sue her so hard...!

Right, well these are all pretty easy, and the point was exaggeration for comedic effect...

It's not funny, but if one wanted to actually be instructional, the fine line now would be something like: can I ask a woman out a third time after she turned me down twice, the difference between telling a woman "You look great" and "that dress looks great on you" + looking her up and down, should you ever tell a woman you work with you're attracted to her, can I proposition a woman a second time if she's still at my place after a date and said no once? If not, can I ask her to leave then? Can I play that song Baby its cold Outside or Blurred Lines at the office party? Can I tell a joke about sex and should I stop when a woman enters the room, or does that make it worse?

IMO, it's not helpful to pretend it should be obvious and everyone who doesn't get it is a laughable idiot or creep. Or to insist that there's a definite line and you're either a "decent person" or a "complete wanker"... most of us are somewhere in between and vary day to day. Or to say "if it feels wrong it IS wrong"... obviously some men have their feels calibrated differently and would benefit from the rules to being more explicit.

Either that, or the answer to all of these is "depends on the woman..." you just need to get to know them, and even then you probably will make a mistake.
