Geordi comes across as an asexual desperately trying to get a girlfriend because that's what he feels is expected of him.
I suspect that there are plenty of blind perverts out there, obsessed with physical beauty, but maybe Geordi is not one of them.
But Geordi's blindness matched with his VISOR registers as synethsesia.
The world around him is a swirling rainbow, and he can identify specific people from how their rainbows swirl.
Gibney's pretty face doesn't matter.
She could have a snout, and Geordi would still "feel" the same, because that is not articulatable to him.
Does the Holodeck seem like swirling rainbows to him, or is it what we see?
How the hell does he read?
