Exactly what you're doing now. Just give horndogs the green flag 🤭
I've seen your posts around and haven't really gotten the impression you were looking for much beyond just a quick exhibitionist thrill. Maybe giving people a bit more info on what you're looking for would help otherwise you're just going to get a bunch of boring "hey" messages.
If you want them you've got to explicitly ask for it or at least post to a dedicated community like TributeMe. People can't read your mind and sending random cumshots and dick pics to someone who didn't ask is very rude(and illegal in some places).
