Is it normal to fantasize about others while in a relationship?
Mostly.Normal for most people
Yes, fantasizing about other people while you’re in a relationship is normal for many people. A fantasy doesn’t automatically mean you love your partner less or want to act on it.
Being in a relationship doesn’t switch off your ability to notice or imagine other people. Fantasies can be fleeting, playful, or simply a private bit of mental wandering—and they don’t have to mean anything deeper.
What matters more is what you do with those feelings and what agreements you and your partner have. If the fantasies are making you feel guilty, pointing to something you’re missing, or leading you toward crossing a boundary, it may be worth thinking about what’s behind them and talking with your partner if that feels useful.
