I hope everyone had a better weekend than this young man.
"I've been seeing this girl for about four moinths. We started getting into mutual hand jobs pretty quick but that's all we do. I never put my dick near her pussy and always rolled away from her to shoot my jizz on myself. Now she says she's preganant. How is that possible? Happy fucking Easter, huh?"
Well, son, it's like this: There's this stuff called pre-ejaculate, commonly referred to as pre-cum. Did you play with your cock and then put your hands into or even near her vagina? Did she stroke your slicked-up boner and then play with herself?
Pre-cum can contain sperm. If your cock was coated with it, no matter which of you was doing the stroking, and that got in - or even near enough to - her vagina that's all it takes.
This is one more reason why parents need to be having serious discussions with their kids. Sorry, young dude. If the two of you aren't ready and properly committed to raising a child, remember you have options.
