But if she's consistently as horny as she acts, 100% on birth control.
She has a higher libido than normal. But isn't displaying any variation meaning birth control is in use.
Mori is basically the opposite. Low libido or at the very least a lot of restraint. But the consistency shows us birth control is in use. Which is to be expected as most American females are on it habitually from a very early age, it gets marketed to them as a way to "control/limit their periods"
Ollie is a decent example of a girl not on birth control. You might initially go "hang on bitch be horny all the time" but nah. There's variation there, she's definitely a pervert but theres a difference between horny and pervert. If you watch her collabs on the regular you'll notice that there's periods where she flirts with other girls less which allows us to get some idea of her cycle.
I frankly don't watch enough girls to be able to provide a comprehensive list.
But look for the variation in the horny levels. Collabs are great for this so focus on those. Assuming of course the girl is at least somewhat interested in girls (all females are bisexual but the degree and what it takes to get them to act on it varies dramatically)
Point is look for the variation over time. The key thing to watch for is for her to have a horny period, a (relatively) calm period then another horny period. You'll need to watch for this a bit over a month. To be able to reliably confirm you'd ideally want to observe their behaviour over multiple months.
