Why do I have no armpit hair?

It probably because you are blond - guys with dark body hair tend to develop earlier than us blonds. Bu your senior year, your armpits will be full - I didn't get a full chest of hair until I was 19 and wo years old - some of us just have to wait.

Armpit hair disgusts me in my opinion, yet I do understand that it, like numerous hair is there to decrease down on order, germs etc. it is why I in basic terms shave as quickly as an afternoon instead of obsessively.

Some guys just don't get a lot of hair. Others don't begin to grow some secondary hair until their late teens. This is a genetic trait, so look at your own family to find out what you can expect. Obviously it's not hurting anything and it isn't a problem. It's just how you are at the moment.

you might just not have a lot. My ex-husband was just not hairy. He had little to no armpit hair and no chest hair to speak of at all. he has hairy arms and legs, but very fair. He is a red head (was... mostly gray or gone now!).
