There's nothing confusing about it. Fem lesbians like masculinity, but love pussy. Which makes a butch lesbian the best of both worlds for them. This is like asking why vegetarians eat imitation [tofu] meat. They want the relative taste/texture of eating meat, without actually ingesting animal parts.
lol @imitation meat, Imitation meat sound so unhealthy yet people who push the idea of eating healthy eating imitation meat.
and there is where the confusion is because vegetarians (or should I say real vegetarians) do not eat imitation meat.
