Our biggest struggle as fallible beings is to abstain from our vices. Everything from sugar to alcohol just tastes/feels too good to easily say no to. It's actually kind of sad. A comedian, Ari Shaffir once said that all it would take to eliminate chlamydia for good is if everyone took the medication and stopped having sex for ten days. Ten days and a whole virus would be wiped out of existence. Still, we can't abstain.
People are probably more addicted to ice cream than sex. Sometimes they even combine the two. Try it. You'll have to wash the sheets after, but that's probably the case even without the ice cream. This nifty tool makes it so you can't get to the ice cream without a code, but if you're determined you're just going to cut into it.
