This is the site for you, if you're interested in learning more about the virtual cornucopia of contraceptive techniques. All your favorites are here -- the pill, the rubber, the diaphragm, the 'snip'... it's like a greatest hits of safe sex!
And such interesting trivia -- I never realized that the sponge was such a crapshoot, for instance. (Up to 36% failure rate -- ouch!) Or that the 'female condom' was so damned complicated.
Of course, it's not all surprises here. Under 'Abstinence', one of the side effects is 'Sexual frustration'. Um, yeah. Amen to that.
