What I've read is more like condoms 90% effective
if used right... that means, 90% of couples who
use condoms for a year don't get pregnant.
Major wrong way to use a condom:
Trapping a big air pocket in that little tip
at the end when you put it on. Pop!
Ways to get preg even if using a condom right:
You pull one off, put a new one on, BUT you
got sperm on your fingers & rubbed it onto
the new one (or into her
... OR,
sperm drips out the bottom of the condom,
onto her, swims back up inside... Drip happens most
when she's on top, hardly at all when the man is.
OR, you use it right, & it breaks.
(I've never had that happen tho.)
I hear sperm can find
its way through the latex sometimes too.
Latex isn't solid at the molecular level,
& sperm's real small...
Condom alone is taking a chance,
you may find out what "fucked up"
really means... Add spermicide & a
diaphragm or sponge.
Unless you like paying child support.
Also think about what time of "month"
it is for her... 14 days before her period
is the most dangerous time, usually.
There were devices for women to test
their fertility level, but the $%!#@ FDA
banned them all because they were only
about as effective as a condom...
The pill is 98% effective. Nothing else comes close.
