God, waiting three months for a shag!? Shagged my partner on 3rd date, not because of a rule but because of circumstances. Live together very happily now. He also: changed his clothes style, bought me expensive gifts and took me away. Because he was trying to impress and court me. It was lovely.
Neither of us were desperate and both had others interested but we were very impressed by each other from the beginning. Still are 🤷♀️
