* "Boy" + "Friend": This is the most common and straightforward way. Sign "boy" (a sign with your dominant hand held palm-in and moving from your chin down to your chest) followed by "friend" (a sign with your dominant hand forming a "V" shape and moving from your cheek outwards).
* "My" + "Boyfriend": You can use the possessive pronoun "my" (sign for "me" with your dominant hand open and facing outwards) followed by "boyfriend" (sign for "boy" and then "friend").
* Contextual Signs: Sometimes, you can use other signs depending on the context. For example, if you're discussing your romantic relationship, you might use "partner," "love" or "significant other" instead.
Important Note: Sign language varies significantly across different regions and cultures. There might be other ways to sign "boyfriend" in other sign languages.
It's always best to learn from a qualified ASL instructor to ensure you're using the correct and culturally appropriate signs.
