Obviously size preferences vary widely - you just have to know your preferences and limits. This toy is 1-3/8" diameter - for my wife it would be 'why bother'. For her 1-5/8 is the minimum, 1-3/4 her sweet spot and 2" when she's feeling adventurous.
But none of that matters - "know thyself and to thine own be true" (or something like that!
This was just way too big for me. I keep hearing that after you have a child then you'll tend to prefer more girth. Is this true? Or do you find that too many dildos are just to big for your liking?
I highly doubt girth lovers tend to be women who have already had children. That is rubbish. Just like saying we are loose after having child. All vaginas are different. Having children doesn't change whether or not you like girth.
