Question
Is there something wrong with me if my penis keeps changing sizes? Sometimes it shrivels up on me and is 2 inches. Sometimes it is 3-5 inches soft. No matter what, it reaches about 7-8 inches hard. I'm 16 years old. Should I see a doctor about this?
Answer
This is very normal. Penis size changes depending on how much blood it's filled with. This is affected by temperature, hormones, arousal, stimulation, etc. There's no need to see a doctor for this.
