This 'incredible potency' (or 'extreme fertility') that you refer to... does it have anything to do with a higher occurrence of 'having unprotected sex' (or rape) ?
Is it possible that among women (no matter what ethnic origin) some are more fertile than others ?
Perhaps those women who are more INCREDIBLY POTENT should avoid having casual and unprotected sex, with multiple partners on a daily basis.
How many of these INCREDIBLY POTENT ethnic women get raped (legitimate rape) ?
Folks tend to be rather overdressed there anyway.
Bet you were thinking of something else eh!
