I'd take the Doctor as a hologram as a partner over Neelix anyday. Not that I'm particularly attracted to him, although I love his character, but he's way more attractive than Neelix. The character, not the actor I mean, just to be clear.
Apparently Ocampans, or at least Kes, have pretty different tastes, although I think Kes was emotionally pure and enlightened to see beyond the physical.
I do find Date kind of attractive. I may be oversharing.
I think if Trek were real, you'd be sharing a sofa with Barclay, talking to Troi about choosing to be in a relationship with a video game over a flesh & blood person.
