I’ve been with my (25F) fiancé (34M) for four years now, and I’m madly in love with him. I’ve never once thought about cheating or thinking of anyone else in a romantic way. He does know I’m bisexual and is (obviously) fine with it, so there’s no issues there. But, as of late, I’ve been having a hard time getting in the mood when I’m with him. He’s very attractive and sweet, kind and caring— perfect guy, really, but I’ve been struggling. I’ve also been reading some sapphic romance books and that really gets me “excited”, but I also feel terrible because it does feel like cheating and I don’t get as excited with him in that way. Is this normal? Like a fluctuation of attraction? I’ll take any and all advice honestly, I’m at a loss and I want to be intimate again and actually be into it.
