Am i too small or am i just dating size queens?

a few women told me i have a small and im 27yrs old, 4.5 inches erect and 5 inches around. One woman told her friend i am very little, another said short and stubby, and then recently i asked a gf and she said i could only satisfy 10% of women with my size. I noticed most of these women are over weight so maybe its them and not me.
