Studies have shown that men are the ones most likely to not make eye contact with the people they talk to.
I'm guilty of this, of course. I rarely look people in the eyes for more than a few fleeting moments. Most often I'm looking around as they speak, as this is how I digest information. Could be that I'll start off watching their eyes, allow my gaze to slide to their shoulder, then look to their hands or body-language to gauge their non-verbal responses...
I've never been called out on it, though. But that's probably because I'm always showing that I'm following the conversation by nodding, pursing my lips, smiling, or knitting my brows together...
Of course, I've always considered eye-contact as part of a challenge, or something that happens when I'm searching for confirmation of a shocking statement.
To force yourself to stare at someone else's face, though? That'd probably come off as completely unnatural. I'd suggest that brief glances at the start of each of their responses is warranted, or when you're offering your own view... but other than that? Wouldn't it just be staring?
Though to ease yourself into even that, get a large pic of your bf's handsome, smiling face, and stare at it for hours on end. Memorize every little line that you see. Get comfortable with the windows of his soul being directed towards you. Try your best to fall for his loving gaze...
But when you meet in person, try not to stare at his crotch. While that might be welcome, it'd probably cause a few awkward moments.
