Didn't r/all and r/popular become identical after they started filtering NSFW from r/all quite a few years ago? I couldn't tell the difference after that change at least. It honestly makes sense to delete one of them if they're the same.
Edit: Never mind, apparently they removed r/popular too.
If the guy protests putting the condom on, I wouldn't trust them to keep it on during the entire act. Stealthing is common enough that it has its own slang term.
However, it's easy for me to recommend withdrawing consent, but in the moment when the guy has already been a bit scary during the condom conversation, it's not always so easy.
Shame on him for completely fucking up the vibe.
