| Yes. What it actually does is generate a one time key for use with this
| session (session key). The session key is relatively small (128 bits --
| about 16 alphanumeric characters worth of data). The message is encrypted
| once using this session key. Then the session key is encrypted once for
| each recipient (using that recipient's public key) and added to the
| encrypted message. So the total size of the encrypted data gets larger
| with each additional recipient, but only a little -- enough for an
| encrypted session key.
| Each recipient is able to decrypt the session key using their private key,
| then use the session key to decrypt the message.

| It means that your key is added to the list of recipient keys each time
| you choose to encrypt a message.

| Send yourself a Bcc copy of the email.
