This is a question for women, not men. For example, I have only my wife's reactions to my Penis Enlargement progress to make a judgement. But as a man with a story, I'll try.
When we were married I was 7" x 5" (note: she thinks it is 9", because she measured me once on the underside -- I didn't correct her). Anyway, I know she was keen on my size, because she would say so. And from what I read of others' experiences, this is a good size even though I longed for bigger, better, more. Story doesn't stop here.
I was into Penis Enlargement of various forms: pumps, pills, and creams with non-routine jelqs exercises of various sorts. I know I made progress over the years visually and self measuring. Many years after we were married I discovered penile
traction devices and started using one a year and a half ago. At that point I measured 8.2" x 5.9" as my starting point. Before I started the
traction exercises, I will tell you that my wife had made comments when goaded about how good I felt inside her, particularly the girth part. So my earlier Penis Enlargement was somewhat successful and mark up 6" girth as a confirmed good thing for women (at least mine). Fast forward.
Over a year and a half later with steady use of the
traction device, I managed to reach 9.3" x 6.6" with even more positive feedback from my wife. Starting about six months ago I noticed how she started fondling my cock more during foreplay -- moving her fingers over the length and grabbing the girth with gusto and admiring glances. Makes me hot writing this down. Then when I enter her she groans and really humps my cock. So don't tell me that 6" is too big for women when my woman gets charged up when I ram six and a half inches of girth meat into her.
Conclusion from a sample size of one: go for as much girth as you want and the women will thank you for it in touching, admiring, groaning, and tears of joy (maybe to a point, but I'm not to that point yet).
