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 .
