I've created Category:Women in sexually appealing postures on Commons.
This is a matter of correctly classifying the sort of pictures we have discussed here which have this quality, sometimes inappropriately.
Category:Men in sexually appealing postures is obviously required also.
In terms of the category tree on Commons Category:Women in sexually appealing postures is one of four branches of Categories: Women,Posture, and People by setting
Category:Girls by posture (birth 13 (puberty)) Category:Adolescent girls by posture (13 - 17 years) Category:Women by posture (18 - 59 years) Category:Old women by posture
I think this exercise should serve to clarify the nature of the images we are hosting and should be an aid to further discussion.
