The intricacies of the female body are fascinating, and it's a shame that they're often swept under the carpet as topics unfit for discussion. It's a very "out of sight, out of mind" situation, which is unfortunate because it seems to lead to a lot of misinformation and ignorance, which then gets passed on to the next generation.
As for societal taboos, they definitely still exist, although I do think things are slowly changing for the better. Men are generally curious about what they don't know, and some definitely make an effort to understand the intricacies, which is admirable. But there's still a lot of room for improvement. Some men are squicked out by periods and pregnancy, and it's often seen as "gross" or "not something guys want to think about."
I do believe there needs to be more education on these topics, especially for younger males. It'd be nice to raise a generation of men who aren't squeamish about these natural bodily functions and who can appreciate the wonders of the female body and what it's capable of! We're halfway there, I think, with many guys being quite open-minded and informed, but there's still a significant portion who aren't. Here's to hoping future generations of men are more understanding and supportive!
