It is much easier than that. Just use a condom. It the easiest thing in the world to use. Cheap too...but somehow many people can't do it.
Condoms don't always work.
Yeah...they only work about 99% of the time, so that isn't good enough for you.
I've noticed that women in the black community are pretty screwed up. Most of them think money is more important than relationships. They tend to get knocked up and pick the best provider candidate instead of being more choosy about who they sleep with.
This comes from never learning good values growing up.
Most blacks learn to think only of themselves because that's what everyone talks about and that's what they see in TV shows and in movies.
Just about all black themed movies are about hookers, pimps, drug dealers or slavery.
They never learn about being successful families and teaching your kids that family is very important. It is the roots of any good society.
