On the one hand it's often said that it's the person inside that is most important, not what they look like. However, I suspect that while the character of the person is extremely important, physical attraction does play some role in a successful relationship. However, I could be wrong! Actually I admit I am not sure about my views on this issue at the moment.
Here's an example - if you met someone who was extremely compatible with you in terms of your values, emotions etc but you weren't crazy about them physically, should you overlook the fact you aren't particularly attracted to them, and have a go at a relationship anyway?
