A top, is a person who is giving during
sex not matter the position. Opposite from a bottom, a person receiving during
sex no matter the position as well. A switch is both of these things. A top is different from a dom (a dominant person) the main difference being a dom being the person on top during
sex and a top being the one giving during
sex.
A difference between top, bottom, switch, dom and sub, is tops, bottoms and switches, are only same-
sex/same-gender, enby/m, enby/f, enby/enby couples, doms and subs are m/f .
