This has been discussed extensively on both the MGTOW and the PUA sites.
I'm totally with you on the avoid temptation at the get go, part, and that's easy to avoid in a casual sense-- it's within a relationship that it's hard (if long term commitment hasn't been yet established). In that case, both people need to be committed to not putting themselves in murky waters (if they've agreed to putting off the sexual element) not just the woman. We all get weak sometimes.
I don't want to derail this thread, but what is up with this MGTOW stuff?! Don't get me wrong, I understand what drives men to that kind of thinking (I sometimes slip into the female version of it) but just abandoning women-kind, and a man's own desires for relationship and family, is just dumb. It's really the perfect counter-extreme to the man-blaming, "strong + liberated" female victim mentality. The solution is always in the middle. It grieves me even in a personal way because I struggle to find good men and sometimes (as aforementioned) start to think I'm just better off leading a single life. It's the same deception that well-intentioned individuals of both genders experience, but it's a lie.
And to the OP (since I've only commented on side issues), I do think raising boys to be open emotionally is important-- not shaming them for expression, but talking them through beneficial ways of channeling that (as I would with a child of either gender). This is something, honestly, that I've witnessed mishandling of by fathers just as much as mothers though. My Dad and brother are perfect examples. My Dad was pretty absent (working + traveling) but he always frowned on crying or being hurt with both my brother and myself. I think it was because that was very ingrained in him, and as a result he had no idea what to do when we were upset or sad. My brother specifically was also pretty discouraged from other forms of emotion that I wasn't, and expected to be stoic/independent younger.
Now that my brother is a father (and a hella great one too, I might add) he's better about these things than my Dad was, but there are still moment that I've seen him shame my nephew-- usually when he's stressed (he's 6w7) and in regards to not instantaneous obedience (my nephew isn't even two yet!) or when he senses any sort of defiance. He reacts too strongly, too quickly, and (though he's an amazing Dad is almost every other way) I do think it will affect my nephew in the long run.
I suppose that's called personality though, yes?

I know I wouldn't be who I am if my parents hadn't screwed up in the ways they did-- the truth is that all kids sustain hurt and are messed up somehow, there's no preventing it, only processing it and turning it into growth.
