One girl I know is really horny. She doesn't show it but once the session starts she gets into it. Her clitoris really shoots out of the the cave. Its really sensitive and you can't directly rub it.
I noticed the first session of the day for her is more mild. If I see her later during the day she gets hornier. She wants to cum more, clit rubbing, finger fuck, leg lock around the hips thing. She tells me most guys like HJ and BJ more than FS. IDK, just passing the story.
Each person is different so results are different. Like others said some have more energy in the morning.
