My lover showed me her toy collection after I told her that using toys was one of my fetishes, the biggest dildo she has, is the Doc Johnson John Holmes realistic, I was suprised how huge it is - 7.75-8inches in cirfumference, 12" overall length, 10" from balls to tip. I have some John holmes pornos so we watched them while I used the toy on her. It slid in surprisingly easily but when she tried to suck it, it wouldn't fit in her mouth. Comparing the dildo with John's cock it is clear that it has been somewhat inflated from his real size: Women never seemed to have a problem blowing him which must mean a cirfumference of less than 7" and if he was really 12" long, it would hang just above his knees whereas in his films it hangs just below halfway down his thigh, I think that in reality he was closer to 10" I checked other pornstar dildos' dimensions with my porn collection, the biggest exaggeration is the Dick Rambone 18incher, (18inches hangs below the knee on an average sized man! in reality he looked as long as John Holmes' 10-11" If anyone could try the real thing I'm sure that they would feel cheated but because that would never happen, I'm sure that they don't mind the extra few inches.
