Don't worry about it, you still have plenty of time to grow. Your penis often goes through its own growth spurt between the ages 13-15 and again between 17-20.

Don't worry about size. I know your friends will rave about how they have king kong in their pants, but most likely they are full of it. And there are a lot of women who prefer a small-medium sized penis.

Relax :)

I also hit puberty pretty late, started getting pubic hair at age 14. It just seems like 5.5in's isnt big enough for doggy position or anything, just seems like it would be hard to tap in dat position with only a 5.5in penis.

Don't worry, you still have plenty of time; it'l come. (no pun intended)

I didn't hit puberty (at least, pubic hair growth) until I was late 15/early 16. At 20 now, what are the chances there's growth left in me yet? I still can only grow very weak sideburns and the hair's more like fluff than anything; chest hair's only been growing for the past 18 months/2years, as has back hair.

I haven't noticed any change in height for a couple of years, so that worries me that i've stopped growing.

I think if you hit puberty that late, that there is still a chance. How great of a chance? Can't really say.
