You start realizing older women are a lot bolder than young women. Older chicks at work will straight up molest you. This married 50yo milf type at work...she'd always be real close when talking to me, and touch my shoulder or arm. One day she straight up grabbed/caressed the side of my neck and then was like "oops, I was trying to touch your shoulder..."
You can also tell when a lot of chicks are having sex flashbacks or thinking about fukking you. With a guy, I know if I see a chick and start imagining fukking her there's no way to tell what I'm thinking since I'm just looking regular/deadpan. But for instance a long time ago I was telling these chicks at work how I managed to tone myself by running at a local track. They were asking pretty normal questions, we were having a normal conversation about cardio when I noticed one of the chicks who hadn't said anything was sitting with her legs open (she was wearing dress pants, not a dress/skirt lol) just staring into space. Then, as if out of a dream she said "can you run fast?" We was like
I noticed her snap out of it and realize what happened, so she stood up and started laughing and trying to act normal but nah. It was too late lmao.
