You CANNOT show them a male character that would jump at the occasion of boning their childhood friend/love interest/any girl interested in the MC, because that would hit their insecurities.
It's the same reason why you never see men other than the MC having a love life, or that within harem manga/anime the girls not chosen almost never move on to have a love life.
ANY WHIFF of competition/needing to actually struggle, no matter how nonsensical, is poison to them, and consequently to any sales pandering to them,
