Mrs. here, I could only pick one range... so I chose the first. but up to about 7 in. is good for me, anything larger and it hurts with every stroke.
I also enjoy a thick one.. more contact on the sides.
If a man knows how to please his partners, then that is the ticket... I am not afraid to tell anyone what feels good and what don't.
If they don't know, how can they guess? Men are not mind readers.. and may need some insight sometimes.
