There likely is a significant difference. I don't see why you'd have longer life without dick or acidised vulva, but you could and many folk have die from blood loss or shock. Even under close medic overwatch, it still happens. And I bet the social effet is like declawing for cats (btw you uphold this, too? @FELIDAE) - bad.
Sex is always a result of evolutionary, hormonal and social pressure.
So are everything else. Also hangs on where it is, but in my happenings, social pressure goes to chastity.
