Slang terms for this line of hair include "happy line", "happy trail", or “treasure trail”. Although the development of abdominal hair normally begins during puberty it may also start later, between the ages of 20 and 30.
How Many Guys Have Happy Trails? According to Wikipedia, about 55% of men grow lower abdominal hair. But the majority of men grow hair all over; only about 19% of men naturally grow a straight line of hair in the lower abdomen area.
That is Tanner stage 5. Aka the last stage. Boys typically have 1.2 inches of growth left after the start of 5 (1 year left) a happy trail domes in 7 months after the start of Tanner 5. If you just recently got your happy trail you should have 1/2 an inch of growth left.
Like most body hair, it's more common to find happy trails on guys than gals. The hair itself also tends to be darker, thicker, and generally more abundant on guys. But if you're a dude and don't have a happy trail at all, don't worry about it. It's a fickle set of follicles.
Abdominal hair growth does not indicate the end of growth. That's just a myth. Different parts of puberty occur at different times and while there may be trends, there's no definitive sign that you're growth has stopped.
Boys finish their growth and physical development. Many may not develop facial hair until this step in the process. Pubic hair may extend out to their thighs, and some boys may have a line of hair up to their belly button. Most boys finish growing by age 17, but some may continue growing through their early 20s.
Getting a happy trail does not mean you stopped your growth spurt. I have seen a lot of boys getting facial hair at 14, but that doesn't mean they stopped growing, boys can grow until they are 16–17, so just try not to worry about it, and take good care of yourself.

Although the development of abdominal hair normally begins during puberty it may also start later, between the ages of 20 and 30.

No — shaving hair doesn't change its thickness, color or rate of growth. Shaving facial or body hair gives the hair a blunt tip. The tip might feel coarse or "stubbly" for a time as it grows out.
Shaving, whether it's your legs, armpits, or pubic area, is a personal choice. You certainly don't have to shave before sex if you don't want to. Shaving pubic hair (or not) is a cosmetic preference, and it does not mean you are "cleaner" if you shave. If you do prefer to shave, try not to do it right before sex.
Pubic hair is nothing to be ashamed or embarrassed about since it serves multiple purposes. Right from providing a cushion against friction that can cause skin abrasion and injury to protection from bacteria and unwanted pathogens.
Another study that explored other determinants of sexual attraction concluded that women also rate men with hair in the chest and abdomen as more attractive (Dixson et al., 2003). Data clearly show that women prefer men with body hair, a direct indicator of sexual maturity.
Here's a good—if not obvious—rule of thumb: Depending on the extent you trim your chest, your stomach should be shorn to at least the same level, probably even shorter. It's a visual thing, really. As for below the belly button, don't hesitate to simply pick up a trimmer and go to town.
Lots of women have a happy trail. In case you didn't know, the happy trail is the area below the belly button. Unless the hair there you are getting is very thick and dark, you shouldn't have anything to be concerned about.

Children with precocious puberty may grow quickly at first and be tall, compared with their peers. But, because their bones mature more quickly than normal, they often stop growing earlier than usual. This can cause them to be shorter than average as adults.
Typically, boys will tend to grow an average of 3 inches, or 7.6cm, each year during puberty. In general, a boy's age during puberty will not affect his final height, but it will affect when his height growth begins and stops.
This is a time of many physical, mental, emotional, and social changes. Hormones change as puberty begins. Most boys grow facial and pubic hair and their voices deepen. Most girls grow pubic hair and breasts, and start their period.
