I posted about this before, but I got one of my exes pregnant twice. I used to always pull out. I am the opposite of
@skeetsinternal, I always c my nut. I actually have a fetish for seeing my juices of life on a woman's skin lol.
Anyway, I asked my doctor how this could be possible when I always pull out. He asked me how often I go multiple rounds with my girl in one night. He said that if you ever go multiple rounds MAKE SURE YOU PISS BEFORE ROUNDS.
He said the pull out method is very effective. Basically as effective as wearing a condom. This is because pre-cum has no usable sperm in it....UNLESS YOU HAVE A EJACULATED RECENTLY. If you are going multiple rounds, after the first, if you have not urinated, there is an extremely high chance that there will be LIVE SPERM IN YOUR PRE-CUM. Since you can't really tell when your pre-cum is released, the pullout method is then rendered useless.
I haven't gotten a girl pregnant since he told me that...
But as you see, just merely pulling out is not at all full proof.
