I am intangible
Once given, I can never be regained
I am always given as a pair
I can give a gift of my own
Everyone has me exactly once
I ask you: What am I
I am intangible

How about:
Virginity:
Not a real, physical thing. You can't un-boink. Can result in children. You have it from birth until you lose it.
Edit:
and of course, it takes two (or more) to tango ;)
My guess is
Life.
It cannot be regain after death.
Its intangible.
Given by two parents.
You can give another life.
And you live exactly once.
My guess would be
Love
Explanation line by line:
I am intangible
Love is an emotion.
Once given, I can never be regained
Its hard to let something go you love.
I am always given as a pair
Love is always between two things.
I can give a gift of my own
Love can give the ability to reproduce.
Everyone has me exactly once
The love of your life.
My try: I am
a name
I am intangible
A name is intangible
Once given, I can never be regained
Once you give a name to a baby you can't get it back, that doesn't makes sense.
I am always given as a pair
You get a pair of firstname/lastname on birth
I can give a gift of my own
You "gift" your lastname to your child
Everyone has me exactly once
Everyone has only one name
I would say,
death
I am intangible
Can you really touch death?
Once given, I can never be regained
It can't be regain as it cant be lost
I am always given as a pair
Clinical death and brain death
I can give a gift of my own
If somebody dies can leave some inheritance to his family and that might be consider as gift (especially if person who died is some far relative who you even didn't know exist), or maybe it is red herring
Everyone has me exactly once
You can die only once
I ask you: What am I
Pretty similar to Izzy's answer, but my guess is:
Birth
My guess is:
A brain.
I am intangible
Your brain is inside your head, and therefore not tangible (by you, at least).
Once given, I can never be regained
You can have a brain transplant, but you can never have your own brain again.
I am always given as a pair
The brain is divided into two lobes - thus, a pair.
I can give a gift of my own
Knowledge is the greatest gift of all.
Everyone has me exactly once
Metaphysically, we only ever have one mind.
