It makes a difference if you can maintain it. I have measured 7.25” once but it deflates without constant stimulation. Maintaining an erection is really important. If I can’t stay firm, I find it nearly impossible to penetrate a tight pussy!
Flaccid girth is important to because, supposedly, is what is visible and makes a first impression which won’t be the case with a turtle hiding! It’s not that easy to measure but I have been nearly 6.5” when warm and under no stress. I was a real turn on watching the girl that I dated try to wrap her hands around it without squeezing and hear her complain that it was too big to fit in her mouth!
Hard or soft, girth matters. For me anyway!
