That is a question lots of people are facing in the world today as techonology expands and broadens more and more.

As for being in a committed relationship and talking with other men or women, as long as those feelings harbored for the other person are strictly friend feelings and the conversation stays as such there is no problem. I have been in very serious relationships and still talked with my guy friends and hung out with them, the line only gets crossed when inappropriate advances and such start going on.

As for the other person viewing these conversations, that is tricky, you are allowed your privacy, and your partner should trust you that nothing inappropriate is going on. But then again if those lines aren't being crossed there is nothing to hide.

I hope this was of some help, lol I haven't had my coffee for the day yet so I"m hoping this makes sense :P

Peace
