When it comes to talking about suggesting the libido, there are a few synonyms that can be used to express this idea in different ways. One possible synonym might be "intimating desire." This phrasing suggests a subtle, indirect approach to the topic of sexual desire, perhaps hinting at it or only mentioning it indirectly. Another option might be "invoking passion," which implies a more direct, forceful approach that seeks to elicit a strong reaction in the listener. Other possibilities might include "hinting at lust," "evoking sensuality," or "alluding to desire." Each of these phrases can be used to suggest the presence of sexual desire without explicitly stating it.
