Here are some examples:
* Meu namorado é muito legal. (My boyfriend is very cool.)
* Ela está namorando? (Is she dating?)
* Eu estou procurando um namorado. (I'm looking for a boyfriend.)
There are other less common ways to say "boyfriend," depending on the context:
* Companheiro (Companion) - Used when referring to someone you're in a committed relationship with, but not necessarily a romantic one.
* Parceiro (Partner) - Also used for a committed relationship, but can be used for romantic or platonic relationships.
* Amante (Lover) - This word carries a more passionate and romantic connotation.
The best word to use depends on the specific context and the level of formality.
