SEATTLE, Washington - Everyone knows why women lie about birth control and get knocked up - but why do guys let themselves fall for this? Why perform this (hopefully, I think) massively life-changing event so casually?
Unless a guy is doing something exotic like holding his laptop in his lap and hoping this damages the sperm, all he has is vasectomy and condoms. If you haven't had a vasectomy, and you have sex without a condom with a woman capable of pregnancy, and you're not in a permanent-ish (e.g. marriage) relationship with the woman, you're either extremely irresponsible or you want to make a baby. Most contraceptive claims a woman makes in these circumstances should be ignored.
I'm coming around to the idea that a lot of guys want to make the baby, even if it's a semi-conscious or unconscious decision. I think a lot of people are like me, they procrastinate and waffle on certain large decisions in their life e.g. who to settle down with, or whether to have a child at all. Having sex without a condom in these circumstances has a couple advantages: (1) you get to have sex without a condom, which I assume is more pleasurable than doing it with a condom and (2) you could have one of your Big Life Decisions made for you by fathering a child with a particular person.
