If that's true, it confuses me about one girl I dealt with earlier this year. She wasn't giving me good eye contact and so I interpreted it as a anxiety or nerdiness. Nerds don't look at you when they speak, they move their eyes to think about what they want to say, and this girl was a genius, so extra nerd factor.Another very reliable sign of high interest...the girl acts very nervous...gets flustered and stuttery and/or attempts to avoid eye contact with you altogether.
When I was around her physically, she'd show the sexual tension/anxiety behaviors, but she was afraid to go forward in a relationship, from a prior relationship. Would an exceptionally high interest level empower a woman to overcome baggage from prior relationships?
