Fleshly desires==Evil social communication?

Once you were not a people, but now you are God’s people; once you had not received mercy, but now you have received mercy. Beloved, I urge you as aliens and exiles to abstain from the desires of the flesh that wage war against the soul. (1 Peter 2: 10-11)

A classic antinomy: we have this very good thing happen to us (we are now God’s people) and we have this very bad thing happen to us (we are now alienated from the world in which we live). Paul tells us to look above, to where our citizenship now resides. The author of 1st Peter urges us to ‘abstain from the desires of the flesh.’  I wonder what he meant by this (it’s not obvious that he means engaging in sexual behavior).

The letter has named these sins specifically:

Everyone should be quick to listen, slow to speak and slow to become angry.

If anyone considers himself religious and yet does not keep a tight rein on his tongue, he deceives himself and his religion is worthless.

Rid yourselves of all malice and all deceit, hypocrisy, envy, and slander of every kind.

So I think it would be fair to say the author specifically has in mind anger and slander and other sins involving social communication.
