sit down with her and let her see what she likes. when VHS porn tapes came out in the 80's, my wife watched some at her gfs house down the street one night. came home, woke me up by sucking my cock, and had to have it NOW! told me all about it afterwards. couple nites later, she brought them home for me to see. she had quite a cock fetish for awhile and cock worshipped me. told me she always thought I was large, but now she knew for sure . gfs were wishing they had a big one at home and she blurted out that she did. they all got jealous.
