Glad you asked. (This is super f**king stupid, but I'm doing it anyway)
So there's something called tops and bottoms. In the homosexual community, tops usually pair with bottoms. (Their names come from their...position under the sheets) A top is usually someone who'll rail the other, while the bottom is the one who wants to be collared and dominated. In say gex, the two main holes you'll ever use are the mouth and anal. Anal is often a good choice when you want a more relaxed experience, while mouth is for an intense one.
