Am I Polyamorous or Just Uninspired?

Dear Dr. Betty
Now 21, I have been heavily curious in exploring different acts of sex since I first started masturbating - whether with males, females, multiple partners, role play, manual, fetishism, fantasy, and so on. It would first take an imaginative form, (and regrettably I'd have sought out pornography to fulfill it) but eventually I began to physically experiment with my fellow friends which gave me much excitement and enjoyment. My appetite for new sexual experiences merely grew.
