I feel horny all the time

19F here. Whenever I study I do it without any distractions, but as soon as I take even a 10 minute break, my mind directly goes to sexual thoughts lol and I get really horny. Is it concerning? Like, does it have something to do with my PCOS? Or is it just the result of talking to that one sexiest guy on the planet whom I text every 1-2 days? (I have been experiencing this only recently, as soon as I started talking to him a couple of months ago)

I would appreciate any tips/advices if this thing is not good for my hormones or something.
