I am interested in hearing from girls or their husbands on prefered dildo diameters. Seems about 60% of the manufactured range are around 1.75" or smaller so perhaps this is already an indication on what majority prefer.
My wife started years ago with a 1-1/2" diameter dildo and has progressed to 2-3/4" these days although ones this size are still quite a struggle to get comfortable with. For her it seems 2-1/4" is not too tight and not too loose and fits her like a glove.
Would like some details on the range of sizes you have used and which sizes hit the sweetest spot. I am also quite interested to hear from size queens.
