Something people like me do for reasons not always religious. I'm abstinent because I don't wanna be that girl who got pregnant when she was 15 and now has a McJob.

Abstination:
Not a real word in any language. A composite of Abstinence and the suffix -tion.
-tion is used to make a noun an action or process. It may also be used to mean result or consequence.
Abstain is to refrain from something by one's own choice
Abstinence is the act of... implying the practice of refraining from indulging or desire, action on the noun abstain.
This means that the -tion suffix has been miss-applied to a noun when there is a correct version of which is already a defined word.
First use was by the religious right in a Moral Majority news letter.
This would bring us to another word:
Ignorance: The lack of knowledge, information or education by choice; a state of ignorance.
Logical conclusion: The moral majority was created by god during the period of "Intelligent Design" and gave them the ability to choose ignorance.

basically waiting till you're married to have sex. strangely popular now that the jonas brothers do it - and because edward cullen made bella wait.

To practice of being abstained from sex for a long or short period of time.

A choice. Choosing not to do something that you want to do. Self-control.

Not having sexual intercourse

It's a choice god dammit. Who cares if someone is a fat churchie, an atheist, skinny or whatever. It doesn't matter. If someone chooses abstinence good for them, if not, shut the fuck up.

Sex can wait, masterbate!
