Is there a safe medical way to increase my girth of my penis?

Penile girth: No: there is no way to increase the girth of your penis - some physicians advocate injections of fat, but this is very risky and rarely successful.

Penis size: I've had patients note that use of ED meds like, viagra, Levitra (vardenafil) or Cialis causes their penis to get larger. This maybe just that feeling insecure about sex causes some mild ed. Sexual satisfaction has little to do with penis size and more to do with the relationship and finding out what pleases your partner. As the song says, "its not the meat, its the motion".
