I will vote for "yes".

I don't care about other's sexual orientation. What others do in their bedrooms are never my business. However families with traditional marriage normally carry responsibilities such as raising children, which is the future of our society. I believe the family benefits for traditional marriage relathionship is a reward for taking the family responsibility and contributing to society as a whole.

Again, what people do in their bedroom is their RIGHTS, whereas BENEFITS has to be earned.
