Where to begin? By being candid with yourself, and that you want to explore, and then finding a partner, a friend, a one-night stand, whatever. You'll probably want to taste both roles, insertor and insertee: you might find one more meaningful for you, or you might like both.

I should mention here that all your explorations are meant as enjoyable adventures and as good experiences. If anything turns into hard work, or if you seem driven to ignore your sensuality, and speed on in haste instead, or get worried and upset, it's time to stop or to start over or talk to someone. You can't force love, it unfolds. Often things have to be learned, but if this is not enjoyable learning it's probably not for you. Curiosity is your best bet here, and leave your seriousness at the door - sodomy is an extra, not a pain in the ass.

First, let me explain the basic position and motions that go with them, then I'll discuss matters about the ass-person, the penis- person. Let me go through each position, the motions that can be used, and its advantages and disadvantages; these, of course, can only be explained approximately, as people vary in what fits for them.
