I see both sides, I definately agree that you need the attraction before having a relationship with someone.
For me, my story was almost identical to Casadalinnis. To be honest, I was not initially physically attracted to my current bf at all. He was opposite to what I normally am attracted to, and on paper excluding personality, there are better options out there.
We were friends and things grew over the space of a year. As I got to know him more as a person, I started to care about him more, he's just an absolutely beautiful person inside. Maybe it's the hormones
but now I find him pretty damn hot!
We've been together for three and a half years, he makes me so happy and I love him
So it is possible to find someone become more attractive in your eyes, BUT that may not necessarily be the case for you and for me it was gradual.
I wouldn't suggest pushing it. Maybe just be friends and if things change later then it will. But there's no point forcing it now.
