Are there any laws restricting the way i can park in front of my house in Virginia?

Well, since your friends do it, it MUST be legal! Everyone speeds too, does that mean its legal? Your dad is right. You must park horizontally with your entire car a few inches from the curb. The cul-de-sac is not there for you to park your vehicle like that, it's there to A. place more houses in that area and B. for people to turn around. If an officer saw this, they could ticket and even have your car towed.
