Does Blood Type Reveal Whether a Man Is Unfaithful?

Quick tip: Is he a "player"? How can you tell if someone is a flirt? Some say people who know every trendy restaurant and constantly upgrade their phones tend to be flirty, but relying on that alone is pretty one-sided. Here’s a lighthearted way to gauge a "flirtation index" by blood type (for reference only).

Type A Men's Flirtation Index

Type A men are often quite flirty. They have a strong urge to break out of the status quo and can act on impulse. However, to avoid hurting their families, even if they flirt, they’re unlikely to let things escalate to the point of divorce.

Type B Men's Flirtation Index

Type B men don’t hide their flirty side. Before a relationship gets serious, they may show those tendencies early on, but they’re less likely to escalate afterward. They’re highly physical and quick to make a move.

Type O Men's Flirtation Index

Type O men often separate emotions from physicality. As the mainstay of the family, they may feel that as long as home life is stable, there’s little risk of the family breaking down. This group is often seen as most prone to extramarital affairs.

Type AB Men's Flirtation Index

Type AB men tend to take a more casual view of sex, so even if they flirt, they’re less likely to make it physical. Chatting and playful banter are usually enough. Their strong curiosity can lead to light, teasing advances, but these are typically superficial and not harmful.

Of course, blood type isn’t everything—treat this as a playful reference. Building a trustworthy relationship matters, and you should never lose your sense of self; staying true to who you are is a big part of lasting appeal.
