As an mra would agree that it is in the best interest of young men for us to do this?
Given that the sex drives of young men and women are disproportionate wouldn't you agree that we older men should teach them not to be overaggressive in the pursuit of sex. Whether you believe most rape claims are legitimate or not wouldn't you agree that instilling this in them early would reduce rape claims all together? Asked another way- Would less pressure, nagging, coercion or whatever you want to call it mean less sex or delayed sex but far less claims overall?
I think it is best that both older men and women should teach young men how not to be over-aggressive in their pursuit of sex. And it is okay for both older men and women to talk to girls about setting healthy sexual boundaries.
I also believe that a "lack of a positive male role model" is not always the cause for men behaving abusive. Perhaps a lack of any positive parental role model, and one dominant abusive parent, male or female, can cause all sorts of poor boundary setting, and make their children, boy or girl more vulnerable to abusive relationships.
