signs of sexual tension
1. The nature of the flirting, in general.
2. The eye contact. Is it steamy? Do you look away awkwardly when it does get steamy? Do you look back and it still feels steamy?
3. Deliberate brushing against each other. Do the two of you always find a way to touch—even when it’s not neccessary?
4. Deliberate avoidance of each other. You both try too hard not to look at each other for too long. There are a million lengthy silences in each conversation.
