It’s all in the preparation. Again, I’m speaking from my experience. Never a complaint; only requests for a repeat performance. Maybe I’m the odd man out.
From your pictures thread I gathered you are married, so I’m just assuming since you have got to 7 inch girth you haven’t used it on that many women, obviously there are women who can take it no problem, but I still maintain that the majority of women would certainly say that 7 inches of girth is not ideal.
