Because you are going through puberty, and also you are growing into a man or a woman.
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.
Dogs have hair all over. Including their armpits. There is hair in the area that would be an armpit, but dogs do not have arms, so they don't have armpit hair per se.
I am wondering the same thing. I myself am 16 and like all boy am going through puberty. I have hair all over my body appart from my armpits and is embarressing when my girlfriend see's me naked. I really don't think there is one but I will let you know what I come across.
Yes They Are Disgusting !IT IS NOT DISGUSTING!!!!!!!!!!!! Guys have armpit hair, get over it. Honestly its kinda attractive...
There may be several reasons for this. Thicker hair on one armpit can be one of the causes. One armpit can have an over active sweat gland as compared to the other. Also people who use one hand in excess can have a more sweaty armpit.
Pubic hair. It's use is a little harder to justify. It is just a carry over from our ancestors. A few hundred thousand years to a few million when we were a lot hairier. Same a chest hair, armpit, back. All hair probably started as an insulator when it was colder. We just don't need it anymore and have lost most of it through mutation.
Shaving armpit hair can cause skin irritation, redness, ingrown hairs, and sensitivity, especially if not done correctly. It can also lead to a higher frequency of shaving as the hair grows back quickly, resulting in potential damage to the skin over time.
A grown man has hair all over their body. They have hair on their arms, legs, genitals, back, chest, abdomen, face, hands, feet and scalp. (Unless they're bald)** haha =P
No not completely ___________________ Tattoos do not block hair growth. I have many and my very first one was done on my head. My hair has completely grown in over it and it is no longer visible.
Your penis length if fine, a little over average for your age. As for no armpit hair, there is nothing to worry about. As I'm sure you know, everyone is developing differently and at different rates. Having no armpit hair is not uncommon at your age, and some men do not develop any at all. Just don't be embarrassed about not having any, it really doesn't matter.
It does not pull the hair. Epilators pull the hair but the No No is different. It has a special wire blade called a Thermicon. When you run it over your skin, it basically crystallizes the hair. It's completely painless. The only thing you'll experience is a slight smell. Basically it disrupts communication between the hair and the root resulting in reduced hair growth over time. All you have to do is run it over the skin 2-3 days per week for over two weeks to see reduced hair growth. Get more details about usage and instructions at howtonono.com
The rate of hair growth all over the body is approximately one-half inch per month.
