I will let experienced members and Dr.
Oates respond to your question.
My personal thought is that appearance matters mostly in
Erect state, that\'s when a partner will see it. A
Flaccid 4 inches penis won\'t look good with 9.5 cm
Girth either.
The other aspect we need to think is because of the weight of the 20ml filler, flacid hang will be much better(I can personally testify for this).
Third aspect is
Flaccid volume(pie r square h) is what is checked out by females, there are lots of studies and videos on this.
Just as we as men checkout women with big boobs or buttocks(we don\'t analyse it its real, is the diameter out of proportion) etc. similarly a bulge in crotch will get double takes. In a first date scenario its also a secret attraction switch for those who know how to use it.
