I've fucked approx 100 women over the last 17 years, and with only 1 of them I've literally had to look down to check if it was inside her because she was just so loose. And yet somehow ironically I'd put her in my top 10 fucks of all time, lol... she was amazing and she proper loved my dick (6" long, average-large girth). Albeit she was a very well known slut, 27 years old, slim/athletic body, beautiful face, she basically opened her legs for anything I kid you not.
So, I'm still neutral in this regard of the topics question.
