I really can't believe it's not sidebar material, but once your eyes start to open and you start to understand the reality of women, its imperative if you have kids that you get genetic testing done for you and your kids.
You can guise it under "health-related benefits" that even the most sophisticated hamster will struggle to maneuver around that argument. For the low price of around 99.99 per person, there are a litany of ancestry or health-related spittoon based services that you can sign you and "your kids" up for.
When me, the two kids, and Mrs Thundercock signed up, she even noted, "Fuck, I hope I didn't do something stupid while I'm drunk or I'm fucked." and she's pretty RP aware as far as womyn go.
Fortunately, all my kids are 99.99 percent mine, for the rest of you, if I was a gambling man, 10-15%, probably not necessarily the case.
A close friend of mine got 23 and me testing directly for nothing but health-related benes only to realize that his son was not his son.
She was resistant and after the tests came back, and they RE TESTED, Wife came clean about a drunken night out while overseas in Spain with some random alpha Spaniard.
Chump took it all in stride. Its not public, and he confided in me. "I raised him, he's my son, blah blah... " for the rest of you animals, I can imagine a series of different outcomes. Even if you agree with my buddy, knowledge is power.
Note here : Any show of resistance on the part of your SO means she's at least fucked other men while you were together.
Be forewarned, these truths are tough, but this community isn't about feeling good or sugar coating.
