just like any other art form. In practice, however, it just doesn't work that way.
I get so pissed off when I see someone on a forum or on tumblr or even in real life asking who the "uke/seme" is, who is the more "dominant" in the relationship, or even the MOST OFFENSIVE, "Which one's the woman?"
1. You don't walk up to a heterosexual couple and ask who is the "dominant" one. Healthy relationships are about equality, regardless of the sexuality.
2. There are no women in a homosexual relationship -- they're attracted to men for a reason.
3. Whatever the couple in question does in bed ("uke/seme," "dom/sub," "top/bottom") is none of your go
