Serious question does size matter

[Solestroker88]

So I once pulled this chick in that was bi I subjected her to a very intense tickling around all the vulnerable areas mainly being her feet and her ass hole made her incredibly horny then went to town on her point being I did make her squirt and she said was the first time she had squirt in a year and a half so got me wondering as my size is average with a good bonner talking slightly above still a don’t have anything on one of those strap ons so made me wonder can any one confirm this ?
