In case you missed the text, it says "Why use abstention when you can use protection"
The reason for this pic: There been a lot of emphasis or scare tactics to force abstinence on others. This abstaining claiming 100% safe is completely false. Lets say there's three people. the first two can abstain just fine. The third one is unable to hold out. There goes your 100% effective. If it does not work on ALL people, then it's not 100% effective.
I say that Sex Education teaching about precautionary matters and how to use things like condoms properly a LOT more effective than just abstaining. I'm not sure if this is true or not, but those that are abstaining for the long time might have the "why do i need to learn Sex Ed? I'm not having sex anytime soon" mentality. Get out of that mindset, because you'll need it too in case your willpower suddenly starts to dwindle.
There's always a risk for pregnancy or STD no matter what measures you take. Then again, what DOESN'T come with a risk? You could risk breathing polluted air at any time. When you eat at a restaurant, you risk eating improperly prepared or cooked food. You drive a car, you risk getting into an accident by some dumbass who's texting on the phone while driving.
Just saying, if you're gonna be having a hot fun steaming sexy time with your special other, make sure you do it safely. Oh and use common sense. Without that, it defeats the purpose of everything.
