Hi Doctor... I Am A 40 Yr Old Male. Height

Hi doctor... I am a 40 yr old male. Height is 5'4" and weight 67 kg. My penis size is 4.75" in length and 4.5" in grith while erected. Am I ok with my size? Though my wife has no issue with it but I had 2 gfs before marriage. Both of them told that I am small. One of them left me by showing this reason. Pls answer (I do not have any erection problem)).
