The same as it always has. You should still be growing and that will probably include the penis, but don't expect any big or sudden change. At 14 you should have been having erections for a while so that shouldn't be any surprise. Size can be anything because everyone is different. Your penis is the size and shape it is supposed to be for you.
What to do when penis still in 4 inches even he is 21
If a girl with braces sucks your penis properly there will not be a problem. Basically she should only be using her lips, tongue and throat. Some guys do like having their penis raked by the girl's teeth, but it still should not be a problem.
I just bruised mine snowboarding yesterday, it's still just as bad, but it get's alot worse I'd there is pressure or weight on it,so if you can avoid putting weight on it, I've heard it takes 3 days to a few weeks depending on how bad it is, you should go see a doctor about it if you have any major concerns.
By 18 he should have long had pubic and armpit hair. He may still have some growth in him but that is about over. Kinda scary you know his penis size.
The penis should grow during puberty, but some people start the stages of puberty later than others. Many boys don't complete puberty until they are 17 years old. If you feel that you have completed puberty, and your penis still has not grown, then you should contact your doctor about it to see if they can figure out what the particular problem is. There are a few conditions that may prevent the penis from growing, or can cause puberty to arrest (not complete), and you want to get those ruled out, or if treated.
