Sexuality and attraction can be fluid and vary greatly among individuals, regardless of their sexual orientation. It's not uncommon for people to have fantasies or curiosities that might not align precisely with their sexual orientation. As long as any exploration is consensual and respectful, it's perfectly normal to have various desires or interests. If this is something someone is contemplating, it's important for them to consider their feelings and motivations.
