A contraceptive is s form of "Child Prevention". Methods include;
A Condom: A rubber sock for you knob.
A Diaphram: A rubber dam for your ladies love box.
The Pill: Easier than a cheap chav tart, cheaper than an 'E'
Abstinance: The art of not shagging if you aint old/responsible enough.
The Chav species has dramatically grown as a result of smack-heads not knowing about contraceptives. The time has come for the government to either teach people about contraceptives or cut of evey chavs dick.
