Do I need some type of license to purchase a gun in VA if I am of legal age and a legal citizen etc etc?

I am 21 yrs old, clean record, legal citizen with all the doentation to prove it, but I dont go hunting so the weapons would be kept at the home for self-protection purposes, is there some sort of problem with that in Uncle Sam's eyes? I know Obama doesnt even want us to own pea-shooters and sling-shots but aye, who cares about constitutional right or giving your legal citizens more privelges than Jose from Ecuador who sells nickel bags of dirt weed from behind a local elks club.
