Q & A: Cuz it's mine...

Q: Why can you lick your own fingers, no issues but licking someone else's fingers can cause the dry heaves?

A: The difference likely comes down to psychological factors like perceived hygiene, comfort, and boundaries, as well as some evolutionary instincts.

1. Familiarity and Control
   When you lick your own fingers, you’re fully aware of where your hands have been and what might be on them. This familiarity makes it less gross. With someone else's fingers, there’s an unknown factor, and your brain might immediately jump to concerns about germs or contamination.

2. Social Boundaries
   Touching or licking another person’s fingers crosses into personal boundaries. Even if it’s consensual, it can still feel awkward or inappropriate, triggering discomfort.

3. Germ Aversion
   Humans evolved to avoid potential sources of contamination to reduce the risk of disease. Someone else’s fingers might subconsciously register as a "foreign object" that could harbour pathogens, even if the risk is low.

4. Sensory Factors
   Tactile sensations differ when it’s your fingers versus someone else's. The feeling of their skin texture, temperature, or moisture can feel unexpectedly alien and amplify the "gross-out" response.

5. Cultural and Learned Behaviour
   Society teaches us that licking others is generally unhygienic or odd, so even the idea can make you cringe. Over time, this learned reaction can become strong enough to cause physical discomfort, like dry heaving.

Your brain is essentially trying to protect you, even if it overreacts!
