Cosette, thank you so much for sharing your personal experiences with body hair and hair removal! I think these conversations really help destigmatize and normalize our personal choice in what we decide to do (or not do) with our body hair because it can vary greatly from person to person.
My own experiences for the aforementioned regions are really similar to yours. Personally, I find that shaving around the pubic region is too much of a hassle because the itchiness/ ingrown hairs are just not worth it for me. I may need to find a better solution with a more full coverage bikini bottom... but hard to find good ones on the market that are both cute and full coverage.
