Encrypting with your own public key would mean only you could decrypt it with your private key, making it unreadable to the recipient.

Private keys are never shared; using a recipient's private key to encrypt is not possible and would compromise their identity.

Using the recipient's public key to encrypt ensures that only the holder of the corresponding private key - the intended recipient - can decrypt and read the message. This is the fundamental confidentiality mechanism in public-key cryptography (PKI). No other party, including the sender, can decrypt the message after encryption with the recipient's public key.

Encrypting with your own private key performs a digital signature operation proving sender identity, not confidentiality for the recipient.
