I hardly expect *you* to feel guilt for the misdemeanor (or not) of another party! Just saying that posting intimate pictures of oneself to a stranger over the internet, can have consequences.

If your wife were sending pictures of her lady parts to another man (via the internet), you might see it as a simple biological necessity just like having a period, but I'd be surprised if most married men would be so pragmatic.

So as far as sexting is concerned, I guess it all comes down to what understandings one has with ones spouse and how honest one is regards ones sexual behaviours either within or independent of your relationship.
