Seriously, we always get this in here. IMHO it's absolutely moronic.

Condoms are 98% effective over a period of one year, which means that the odds of not getting pregnant using condoms for a ten year period are (98/100)^10=81.7%. This means that if you use condoms alone there is a 19% chance of pregnancy within ten years. Ditto for the pill at 98% effectiveness. When you use both however, the odds of failure in any given year are .02^2= 0.04%
Thus the ten year success rate for using both methods at the same time is (99.96/100)^10=99.6%
Thus using both at the same time yields a 0.4% chance of pregnancy over ten years, compared to 19% with just one or the other. You are 47.5 times more likely to cause a pregnancy using just one option than you are with both.

Edit: Now that we have the real numbers posted, let's repeat the ten year calculations using those. Perfect use of the pill is listed at 0.3% failure per year, that gives us 3% failure over ten years. Perfect use of condoms is still 19% failure over ten years. Combine the two and you get a chance of failure in any given year of (2%*.3%)= 0.006%.
That yields a ten year failure rate of 1-0.99994^10=.0006=.06% for both methods at the same time. You are still about fifty times more likely to get pregnant using just the pill as you are with the pill and condoms.

Now let's use the typical use numbers. 15% failure for condoms, 8% for the pill. .85^10=.197 meaning that with condoms alone you only have a 19.7% chance of avoiding pregnancy over ten years. .92^10=43.4% chance of avoiding pregnancy for ten years. Combined method: .15*.08=1.2% chance of pregnancy over one year
(1-.012)^10=88.6% success rate over ten years.
Under typical use, even using the combination of both condoms and the pill still results in an 11.3% chance of pregnancy over a ten year period.
 
The hormones in BC pills made me so emotional and hysterical, I stopped taking them after only one month and returned to my normal cheerful relaxed self 2 weeks later. Condoms are obnoxious, but at least they don't have side-effects.

Also, from a guys perspective, unless you really trust the girl I wouldn't rely on her to take the pill every day. When the Male BC pill comes out that will be less of an issue.

😉 Be sure to tell that to your future wife. See how far that gets you. 😀 :laugh:

Yeah, I am waiting too, but I am not choosing abstinence. 😉 I am just waiting till I find the right girl to marry if one ever comes along.
 
Those who state that the pill is 98% affective. It is higher than that. The problem is that too many women forget to take them or take them with antibiotics, etc... There are a lot of things that skew those statistics.

A condom is more likely to break or leak. The true advantage of condoms is protection against many STDs AND pregnancy. But, there still could be manufacturing defect there, improper use (putting it on wrong), or leakage.

Well I've been using either on of the other for more than ten years in long term relationships and guess what, appart from the odd scare here and there, no babies.

If you are with someone for TEN years and the subject of babies doesn't come up I would find that more odd. If you are really that worried then the option is surgery to fix yourself, your partner or both, as you appear to be so sh1t scared of having kids. Ever.

IF we had kids, it would be bad, very bad for everyone involved.

Just how many people are involved? 😕

my parents disowning us for abortion, but if she couldn't cope with that, the next step would be the neglect charges I'm sure would be filed.

Really, we are not ready for kids, we are selfish needy work driven with very private lives who love quiet. We have no time for anything thing that would take time out of our lives.

We recently tried to baby sit her 10 year old nephew. I had to physically leave the house. I was about to kill him. He didn't do a single thing wrong, he was just freaking annoying.
