Masturbating Worries

I've been masturbating for a long time now and I've become aware of the fact that I can't have a orgasm if I finger myself. On the rare occasion that I do, I'm extremely stimulated. I usually come by just rubbing my clit. I'm a virgin btw and I'm concerned whether or not I should be worried if I'll actually enjoy intercourse or fingering with a partner. Is my vagina wired differently?
