The lyrics of the old Cuban songs are not like that at all. The songs of the Machito, Tito Puente, Tito Rodriguez era are not like that either. The aggressive lyrics are a more recent thing and as such they are much more prevalent in hip-hop, rap and reggaeton.
Therefore, I don't think it has anything to do with why there were not more female 'salsa', 'mambo' 'latin' musicians in history.
I think the musicians back in the day were sexist , therefore little to no recordings beyond Celia Cruz and La Lupe (see Jazz musicians example).
Today, live music has experienced such a devastating decline that there just aren't any opportunities for many (men or women) to make an impact in salsa. Most of the music out there to day are recordings from a bygone era where the musicians were sexist.
I totally disagree.
The lyrics of old Cuban songs are very much like that. Doble Sentido. The lyrics today may be more direct as far as eliminating any innuendo or leaving no doubt as to what it might mean but how can you say there wasn't anything similar in the past when you have Graciela having what comes off as an orgasm in the song SI, SI , NO, NO?
All the bands, singers, etc. expressed music that was provocative and had sexual connotations. They invented it. In Cuba, P.R., D.R., etc. Before the 1970s, 80s, 90s, etc.
