I remember when I had hair you could sit on, it was pretty annoying. I think long hair is annoying in general. Right now, my hair is longer than I'd like and I often keep it up in a bun to get it out of the way.
Is your hair dry at all? How often are you combing your hair? How often do you wash your hair?
It might be that your ends are dry and you need to moisturize them or use a product just at the ends of your hair. Combing your hair with a bristle brush will help spread the oils to the ends of your hair but that is probably not enough. If you are washing your hair every day (I don't recommend this), then that can be contributing to your dryness. Also, putting your hair up or braiding can prevent tangles but also help prevent drying out.
Oh and I'd recommend this type of brush to help spread the oils and comb your hair:
