Once had a man that myself and my partner matched with for a potential threesome. The guy was more interested in me than my partner, which almost immediately ruled out any possibility of hooking up with him, but we were giving him some time before deciding if it was a complete no-go.

One evening after we had been chatting for a few days, he mentioned to me he was pretty sure which apartment building I lived in and he was in the neighborhood. He wanted to stop by.

I never told him where I lived and had never had him over before.

Fucking hell, that made me immediately block him everywhere and be a bit more aware of where my keys were while walking home for a while.
