I'd be happy to help, but I honestly don't think there are any differences. I'm dating a man and a woman now, and the relationships are different because the people are different, not because one is opposite-sex and one is same-sex. Yes, this will be new for you in some ways, but I also think you'll find that all the same guidelines apply about how to treat people and what to require in terms of how you're treated. People are people.
