Well I personally would find it hard. I need some sexual attraction there, having a good personality is all good and well, but if there is no sexual attraction there then, its better just to be friends. I find it very intriguing though, that you have that ability, but I mean how are you attracted to someone who is not at least semi-ok looking?
Of course there has to be some attraction. Even I have some limitations.
Like I'm sorry, shallow as this may make me, I'm not dating this guy:

But mostly I find the mind sexy.
Make me laugh, make me feel special and nothing but you will matter.
Honestly, I wish I had a picture of one of my ex boyfriends. And this was when I was 17/18, and at hitting my attraction prime time, and I had untold choices, but to me he was fucking awesome.
