Long penis = female offspring

This whole thing falls apart when you have parents with both girls and boys doesn’t it?

And doesn’t Rocco Siffredi have two boys?!

Hmm.. I have a boy and a girl. For my daughter, I impregnated the wife with a very satisfying deep doggy fuck literally bruising her cervix in the process of ejaculating. For my son, I stealth fucked the sleeping wife and really only got my head in there when I spilled my seed.. Seems to follow the theory in my case.

Wow this is a lot to think about.

And then there is this other theory that women with huge breasts are more likely to have daughters. But that is another talk show, LOL.

Actually you are wrong. Male sperm are faster swimmers, but tire more easily. So the longer they have to travel, the more chance (chance) that the girl sperm wins.

Kind of like the rabbit and the toad.

I was going to say the exact same thing. It wouldn’t make sense the other way around.

Flip a coin it is 50/50 every time. Nothing can be done to change it unless you go to a lab.
