I think this is what simultaneously annoys and pleases some women. Men have one “default” personality that works for either getting laid or getting relationships, and applying it to literally any situation in a blanket fashion will probably just make them seem like a kind, sociable person.

If a guy has feelings for a friend, he chats with her. If a guy sees a woman at a bar, he chats with her. If a guy sees a woman on Tinder, he chats with her. If a guy sees a couple of swingers, he chats with them. Gauging interest as he goes, somewhat subtle flirting (e.g. “you’re beautiful” instead of “I want to f*ck you immediately”), and tactful escalation will always work best. Telling someone you want to make out in a secluded area or otherwise inviting them back to your place will almost always be about what people are saying.

Men do not have enough social leverage in any equal scenario to be super explicit or forward like women can be if they want to get laid or get a relationship. They always have to “make friends”, and likely have to initiate whatever it is they want.
