I would have to confess that using terminology like "substantial beauty" refers to a perception that large female sexual characteristics are particularly attractive. At times, our society has veered widely between a bigger-is-better mentality and our current notion that anyone who isn't bordering on malnourished is "plus sized" or fat. Having a sexual interest in women includes a full range of sizes and shapes. It is only wrong to call that wrong. On the other hand, I know what I like. I worry about those who have so suppressed who they are, including their tastes and preferences, that they cannot honestly say they know what they like.
