Condoms are a very reliable form of male birth control. And, it may be hard to understand, but there are certain fairly popular subcultures where men brag about how many different kids they have with different women.
Because mainstream culture generally looks down upon "deadbeat dads" and doesn't celebrate impregnating multiple women?
Certainly, the first time someone told me they had 12 kids through 8 women, with more kids on the way, I was completely shocked. Even more shocked when I realized he was bragging about his masculinity, not lamenting "What have I done?!"
