For me it's ok as long as the person looks GOOD ENOUGH to get attracted, which is not too hard to get, the rest of the attraction comes and grows with personality. I believe that we humans are beyond the bodies we have. Our eyes are very tricky though, they can be caught by other guys but the rest requires much more to be caught
Trust me, the more you love that person the better he will look (it's not something to be observed though. It just happens), because what you will see on him will be unique for you, nobody else will be able to see that in him or what he sees in you. Others may see muscle, a great shape or whatever in him but when you hug him, when you close your eyes you will see the true caring, giving, loving, the most beautiful person in your life.
Lastly, appearance is important but love is never something as simple as appearance because we can never see it with our eyes so be careful with what you see, it's probably not what you are looking for if what you need is love.
