sometimes i fantasize about being taken...

i'm in grad school, trying to focus but sometimes these intense fantasies come up. mostly about letting someone overpower me and just take control... it's not really something i'd act on but thinking about it feels kinda freeing... like i don't have to be the one always in charge of everything all the time... ends up getting me off a lot when i'm alone though... wondering if this is normal or if it means there's something deeper i need to work through?...
