Is it normal to fantasize about other people?
Yep.Totally normal
Yes, fantasizing about other people is normal, whether you’re single or in a relationship. A fantasy doesn’t automatically mean you want to act on it or care less about your partner.
Your mind can wander, and attraction or fantasy doesn’t switch off just because you’re committed to someone. Lots of people imagine scenarios they’d never actually pursue; thoughts aren’t promises or plans.
People draw the line differently around what feels okay to share or act on, so a partner’s comfort and any agreements you’ve made matter. But simply having a fantasy is not, by itself, cheating or a sign that something is wrong with your relationship.
