I'd rather no one played with fire at all. Children/death as punishment? That's pretty fucked up.
Why are people using the pull-out method and considering it a valid form of contraception (since no one reasonably thinks of it as 'protection')?
Again, I reiterate that your personal anecdotes mean exactly shit. When the statistics say that withdrawal is 80% effective, what that means is out of 100 women, 20 will fall pregnant with it in a year. So the odds are with you (still not something I'd personally want to risk). As time goes by-- 0.8 x 0.8 x 0.8-- after three years, the rate drops to 51% of women escaping pregnancy. This can account for your three-years-and-never-got-pregnant people but they also highlight something else-- sooner or later, odds are, you will get pregnant. Even if it's never happened before. Even if it has. And it has nothing to do with your boyfriend, unless he has a low sperm count.
There are so many reasons why withdrawal is not a viable birth control.
1) it requires self-control which young men may not have yet. And it requires them to know their bodies well enough to know when the point-of-no-return is reached.
2) It requires you to know your cycle (which few young women do). And then it requires you to not have sex during the times you are most fertile.
3) There may be sperm in pre-cum which is left there if the guy hasn't pissed since he last came. That's not a myth.
4) The morning after pill shouldn't be taken repeatedly over short periods of time. It's a superdose of hormones. Even when it's not prescription-only it still requires a conversation with the pharmacist. It's not aspirin.
5) Home pregnancy tests are expensive and the stress of waiting for your period is exhaustive. Shit, I still stress out waiting for my period sometimes, and I'm on the combined pill. Why put yourself through that?
Sorry for the long post, but I don't think you can stress strongly enough that Withdrawal Is Not A Viable Birth Control.
