Though yes that is pretty small and limp, mine has been like that at times, and scared to pull my pants down sometimes.
BUT, mine is pulled back inside me, a lot of the time, keeping itself safely nested and protected... and when I let it out to play, it is like 7 to 8 " in length and pretty fat for girth.
So ladies, just cuz the guy has rather a smalll unit, does NOT mean anything... cuz mine gets big hard and long to satisfy the ladies.
