Yes, of course it's ok to be abstinent! Let's see....no diseases like std's, or hiv, no unwanted pregnancy, and no drama.....yep, it's definitely ok!
It's OK to decide what you do with your body and abstinence usually refers to booze or sex.
It is NOT ok to feel smug about it, or "holier than thou". It's a personal choice, no more, no less.
Of course, smugness is a relative term. I usually abstain from booze and that makes me a better person than Hippy and Otis who don't ... But I'm not smug about it. >:-)
Yes it is.
