Look for aggressive, driven, intelligent women in positions of power who naturally repel men because they're intimidated by them. Also if you're eating her out and her clit is big chances are she's high T.
My ASD baby mama naturally has high t for some reason (apparently common for people on the spectrum), so my son has freakishly large junk and weirdly proportioned fingers (index and pinkie same length, middle and ring same length [way longer than first 2].
The one drawback to this is your son will probably grow up to be a huge asshole, but you'll love him anyways. Probably. My lil guy giggles and smiles at everything rn but I know his brain is a bomb of pent up aggression and angst that'll explode when he's a teenager.
Sorry for ranting; I'm high as shit
