Might be time to change handles to "killerman Sr."
On a more serious note -- hard to say
exactly.
Re: ONS girls, it
seems like it's a little harder to knock a girl up the first night, even if she's ovulating, than it is if she's a repeat partner. Although I wouldn't put down money on it. The thing with ONS is girls are a lot less likely to want to keep that kid if you do knock them up and you're some random guy they know nothing about. There's always the chance they have some FWB they can trap with the baby... I have seen that happen... but fairly good odds they abort or miscarry due to stress if it's an ONS baby.
Re: girls you were seeing on repeat, if you get those girls pregnant, you are typically gonna hear about it.
Things were a bit different a few centuries ago when Casanova had his love children he didn't find out about until years and years later. He was constantly bouncing around between different cities, and there was no reliable way to stay in touch -- women didn't know where he was and had no way to message him. Now even if you're bouncing around a bit, if she has your contact info she can still hit you up with, "Hey,
@killerman -- I'm pregnant and it's yours!"
So, I wouldn't rule it totally out.
But for ONS, it seems harder to impregnate those girls, and they're probably a lot less likely to keep it even if you do.
For FWBs/girlfriends, you're probably going to hear about it if you knock them up.
There are always extenuating circumstances, of course... you are the sexy "good genes" lover, but she also has a stable provider lover, and you put your baby in her, but she tells him it's his (and maybe lies to herself it's his too), then cuts you off without telling you, as she proceeds to lock those resources of his down... Or you knock up the ONS girl who just really wants a baby, or has a family that'll support her, or some guy she can pin it on, or even some white knight guy who will take care of her even knowing she's pregnant with a baby that isn't his.
Those things happen. But they're rarer.
So...
better odds you're not a dad than that you are?
