It makes me feel SO awkward.

So they're jokign about spanking, or very frequently, anal sex. And they have no idea what they are talking about.

If you do anal though, you are gunna stretch your asshole out, won't it be all loose then??
and my every instinct says, it is time to explain the realities of sex and kink!! But i know that that is problematic at so many levels.

For one thing... how do you explain such things!

"well you see... this one time, this er... person i know... told me about her sex life. And she says it doesn't hurt..."

or

"come on now. The anal sphincter is elastic, and highly muscular. It closes back up and you have no trouble controlling your bowels. And no, fisting doesn't make a cunt loose, that is muscular as well, and it shrinks back to normal size..."
**looks of disgust, confusion and/or awe**

or the other day, a couple friends were talking about asphyxiation (one of them being the most open minded and kinky) And they were both like eeee i don't know what they see in that! it is so dangerous!
So i made a semi-casual comment about autoerotic being the most dangerous and safeguards and... lol. I just wanted to say "you must not have tried it yet, because it is so good"

lol. Does anyone else have these issues, where you just want to fix their misconceptions, but don't want to completely 'out' yourself, or gross them out, etc. What do you do?
