I play a mega-hood where aliens are the majority, so their morals are not "human". For some, females rule and males produce babies, but not by sex. they either get pregnant by an alien (and I have about 30PTs), or a townie - even one they've never met. Some males are mean and ugly and impregnate lots of women. Often a playable is "forced" to adopt an alien baby. Sometimes they look really odd, but (true to Maxis non-judgemental function) the adopting parents never think the baby is ugly
