Not if its being used as a defense mechanism. People can sense either end of the spectrum: being too overt or reserved if its not naturally your personality. In any case, I could be wrong. I was merely pinging you as a guess. I can easily be overinterpreting your posts, so I agree, if you think there may be something to this, best to ask someone you know IRL whose opinion you trust. As for me personally, you are asking me to remember back about 20 years. I can only tell you what I distilled from my experiences, I don't remember specifics anymore, Des.
You're not ugly or anything like that. The main thing you have working against you is how intimidating you look. I'd walk up to you and introduce myself, but from your body language and fiercness in your eyes I'd probably find myself taking a step back out of fear of rejection. There are more shy guys out there than you'd think; many guys you wouldn't even imagine as shy are that way; and it all comes down to if the guy can work up the courage to talk to you, which it seems like it'd be harder to do with you.
Try making yourself more approachable, more lively. Hold your chin high, but not so high that it seems like your nose is in the air, if you get my drift.
Hmm, while it is entirely possible what you are saying is true, and that I couldl look more approachable I don't see how you can be so certain in seeing such "fierceness in my eyes" or "body language" without even having seen me in real life. In any case, I don't always wait to be approached, I make the effort to approach as well - if I didn't, I wouldn't get anywhere.
I was basing it off of the pictures you provided us on the second post of this thread.
Try eye flirting. It'll make a guy think you're shy and let them know they have to make the first move if they want to gain any ground.
