It’s an ethnic thing. There are 11 ethnic groups that are known for INCREDIBLE POTENCY. Their women usually get pregnant in the low digits!
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) ?
