tvstrip: in the US - if you father a child, you are liable to support the child through adult hood, assuming you are not married to the mother. That is at least 18 years old (in New York, I think it is age 21.)
So .. in the US, celebrities / professional athletes / etc. - people in the public that are wealthy - women have casual sex with them. If the dude isn't careful - if the women gets pregnant, then the guy is "on the hook" for child support. It doesn't matter "how" the woman becomes pregnant. Including if she takes a turkey baster, "sucks in" the ejaculate left in a discarded condom, and then sticks the turkey baster in her vagina, and squirts it in, that way. I believe it is 18 percent of one's income, per child. (Somewhat sliding scale, as the number increases.)
Do research on PJ Washington and Brittany Renner for an example..
