GPG does not initiate encryption, your MUA (Thunderbird) does. Also, GPG
does not require your own key, but the recipient's key for encryption.
Unless you Bcc yourself or add a default encrypt-to-key in GPG settings,
you won't even be able to read the encrypted message.

What is "the" plugin? Enigmail? In any case, check the plugin settings,
GPG is not the root cause for your problems, the Thunderbird plugin
calling GPG is. Change the plugin settings, or disable it.
