So I'd like to preface this post with the obligatory disclaimer that I'm an adult and in a committed (long distance) relationship for 5 years now. I've had some pretty intense crushes on fictional characters over the years, and some are even involved in my fantasies. My boyfriend is 100% okay with this, and none of them could ever replace them, + he sometimes has these feelings about characters too and considers it normal. However I don't feel normal and I want to know why this happens, so many of the characters are monsters or aliens (think the Predator, or, to get weirder, Moltar from Space Ghost Coast to Coast) but I'd never do anything sexually with one if they were real, they're just fantasies. I've been told this is relatively normal and just a kink but I want answers from someone experienced with sex ed and these types of things, whether it's something to be worried about. I feel like if I get an answer I'll be a lot more comfortable with myself.
