After 15 years-I rarely post on this thread anymore-yep, if you go back you will find many threads on the subject. In the beginning there was little discrepancy-P2/P3 Poser male and female had about the same amount of clothing. It was when second party clothing creators got involved-that they diverged-and that happened fairly quickly. By the time of V1 "The Millenium Woman" there was a huge gap.For many of the reasons already posted in this thread-it never will. It is what the market wants.
I myself rarely make Male renders-and if I do it's likely going to be a look alike character (I.E. a movie/TV star)
