I saw a news article the other day saying that blowjobs cure morning sickness in pregnant women. Something about how morning sickness is actually the woman's body responding to having foreign sperm in her. By giving blowjobs and swallowing the jizz, they're able to acclimate their body to that particular guy's sperm. I didn't post this in the useless info thread, because it may actually be useful info for someone with a pregnant wife/girlfriend.
