Hello It's normal for young adults to not be sure about their penile girth and length. N u r not alone! About 50% males think that their penis is shorter than normal!! While the fact is it's shorter than normal for only 18% or so. I recommend u to go through following article and also measure length of ur penis in FULLY ERECT state by a measuring tape. https://www.healthline.com/health/mens-health/average-penis-size If ur penile length  n girth falls in normal range -- Chill!! If not in the normal range,, or if u don't want to measure ur thing,,  then consult a Urologist / Andrologist - n I recommend physically to clear all ur doubts once and for all! One thing more --- keep it natural and real, don't fall in the trap of unqualified doctors and quacks who would prescibe unscientific medicines which do more harm than good!! ur true love will want u to be tender, loving and caring more than one with a huge penis... Trust me!
