I think in online spaces, so long as you tag your work so that people who DON'T want to see it can avoid it, you're fine. It's not like you're DMing your prudish friends with graphic sex videos and articles. You post on your own pages, and they follow you and know what you're about. If they don't want to see what you post they can mute your articles and keep you as a friend in DMs. They have control over their own experience. You're not violating them in any way.

As for PDA I wouldn’t be bothered seeing someone making out next to me. Lying across my lap is a different story of course. But PDA doesn’t bother me, so long as it’s not full on sex and isn’t so graphic that a minor shouldn’t be seeing it (groping/grinding etc). Making out passionately? I feel happy for them! I usually have headphones on anyway.

I think people who engage in PDA should be ok for people to want to watch them though. If it’s a public space, and you’re making out, and people look at you, you shouldn’t be mad.
