Definitely an average length cock that is thick is the most pleasurable. I always experience discomfort with initial penetration because I am tight. The feeling becomes incredible once he is in me and is thrusting. I become a total whore wanting him in me, wanting him against me, wanting him to kiss me, wanting him to hold me as he makes me the center of his pleasure.Only had two guys top me and both were 6 to 6.5" one had a fat head and skinny shaft and a teenage sex drive behind it. The first guy his dick had a fat base you couldn't get your hand around. He was 45 but we used lots of lube. The ass stretch from him was insane hurt and lust at the same time. So I guess what I'm saying is fat dick is better in most ways.
