Are you supposed to inhale while vaping?

No, e-cigarettes deliver nicotine in a different way than normal cigarettes. Most of the nicotine gets absorbed through your mouth. Many people who switch from smoking to vaping struggle with this because it is a slower act, but you can vape at a steadier pace and vape more often instead of taking a few puffs every hour.

The advantage of not inhaling is that you will experience the full flavor.

So, when you switch from smoking to vaping it is up to you if you want to inhale or not.

Here are some of the ways you can vape:

Mouth-to-lung

This usually works better if you have a smaller vape that has a high resistance coil and uses high nicotine. When you take a draw through these devices it would feel as if you are drinking a double thick milkshake through a straw, it is going to be very tight. Mouth- to-lung draw produces less vapor, basically the same as smoking and that is what smokers want. Here is the technique:

1. Slowly inhale the vapor for a few seconds
2. now hold the vapor in your mouth for a second or two
3. Open your mouth and breathe in the vapor to your lungs
4. Last step is to exhale

Direct lung

This is more suited for larger vaporizers with lower resistance coils that uses lower nicotine. The type of draw will feel as if you are taking a hit from a bong. Here is the technique:

1. You quickly draw vapor directly to your lungs
2. Exhale vapor immediately

Cigar puff

Some people do not inhale the vapor to their lungs and puff on the vape like a cigar. Although not technically inhaling, the cigar puff can be used with high power (similar to DL) or low power devices (similar to MTL). By using this technique, you are still consuming nicotine because it gets absorbed in the mucus membranes. 

Do you still get nicotine if you do not inhale?

If you inhale cigar smoke, you can get almost the same nicotine as you would by smoking a cigarette. And even if you do not inhale, large amounts of nicotine can be absorbed through your mouth.

In the end, it is all up to you if you do not want to inhale and enjoy the flavor more or if you want to inhale and produce more vapor. You make the decision on what you prefer, if people say inhaling vapor is unhealthy then inhaling shower vapor and the aroma of fried bacon is too. Do what makes you happy and not others.
