Tails and making sure someone is legit by pgp

So ive seen the way vendors can sign their own pgp key to prove it is theirs and not someone copy pastaing trying to immitate them. My next question is is that on tails how do you encrypt your public pgp with your private pgp to create a signature to show your are the actually owner.

So type out your message you wish to sign and/or encrypt in gedit highlight it and copy it then left-click the clipboard icon up at the top-right and select "sign/encrypt clipboard with Public Keys" when the window pops up look for the "sign message as" and select YOUR key you wish to sign with and you can choose to encrypt it to the vendors PGP key so it will be signed and encrypted. vendor will see the signed contents once they decrypt. If you do not select a recipient key it will be signed in plaintext. Which is ok if you aren't signing anything sensitive, just trying to prove you are who you say you are. As long as the person has your PGP public key and you signed the message with the right key it will show up Good Signature. If the contents have been altered in anyway after signing it will comeback as Bad Signature, but will let them know the signature was made with the correct key.

I thought you had to "sign" with your PGP in order for it to decrypt with a public key. You shouldn't be encrypting your private key.
