I’m personally kind of a prude and am uncomfortable with oversexualization but I don’t think this puritan, regressive path is the way to go.

the thing to remember is: it's perfectly fine to be uncomfortable with some things--this is a normal part of existing in spaces with other people and it's important to set boundaries for yourself. but in general it's also not necessarily someone else's problem to tailor their online existence to your discomfort.[^1] it's good if they respect your wishes of course, and especially if you're close with them it's probably worthwhile to see if they'll respect some of the ones you have. but with exceptions for the most heinous content it is mostly going to be/should be incumbent on you--at least as possible with the tools at your disposal--to curate your online experience so that you're not exposed to that stuff.

[^1]: this is especially true in what are essentially public spaces like Twitter, rather than smaller and more tailored communities
