Is it normal to Fantasize other people while married ?

This may sound bad.. but I’m very bisexual I lovvvee women and lovvve men.. soo my husband “game” is very strong and it feels good but it’s not enough to make me cum.. so we use toys.. I have to have clit play to get off I’ve always been like that.. but here of late for me to actually cum even while he’s using a toy I fantasize about have sex with a woman.. I don’t want to hurt his feelings so I’ve never told him.. I also feel bad.
