Licking lips
This piece of body language is frequently misunderstood in movies and tv shows, characters may intentionally lick their lips to attract another person but this rarely happens in real life.
most of the time people don’t lick their lips on purpose, it’s almost always unconscious licking your lips is a reflexive reaction.
In other words, you do it without thinking or choosing to lick your lips but what causes this reflexive reaction when you’re attracted to someone your brain jumps 10 steps ahead you start thinking about physical contact about kissing this person so your brain becomes hyper aware of your lips.
Are they too dry, do they look cracked, you can’t really see them, so you unconsciously lick your lips to make them more appealing.
Now, if you see someone licking their lips pay attention even if it is unconscious this person may be giving you a sign.
