Is dirty talk considered cheating?

Anonymous
Okay, this is the scenario.

One of my closest friends (whom I will call Friend A) and I are really comfortable with each other. However, his best friend is my ex, whom I dated for over 5 years in the past. Though we contemplate on how it would have been if we hooked up, we never acted on it because of our loyalties to my ex.

However, because of this, this created a strong sexual tension because it is 'forbidden'. Recently I've gotten into a new relationship and its rather fresh, but even though I now have a boyfriend, Friend A and I began to chat more intimately about what sort of sexual things we would have done with each other, naughty scenarios and stuff. Very detailed too.

I know we will never act on it, but does this dirty talk behind everyone's backs considered cheating? Or is it really not a big deal?

Thanks for the feedback everyone! Friend A and I have called it quits in terms of the teasing, especially now that this new guy is starting to become serious for me. =)
