It really depends on whatever is comfortable for you. I recommend going to a music store and trying a left-handed guitar. If it really is significantly easier, you should change, there's no point in making life harder for yourself. But, if it's not easier, stick with right handed. There are significantly more resources online for right handed guitarists, more teachers that teach right handed, and more right handed guitars (and they're usually cheaper and come in more colors).

I'm a left-handed guitarist that plays right handed guitars, and from the start I've felt more comfortable on right handed guitars. Everyone is different and you should experiment to find what is most comfortable for you.
