Answer:
Most girls do not like a lot of body hair, and mustaches can even be painful while kissing or *ahem*, other things….

You should consider yourself lucky

Answer:
Different guys, different hormones, different genes, etc. Be thankful you have little body hair as it is a big turn-off for most girls. I can't grow one either and I am glad because I hate to shave.

Answer:
It all has to do with genetics. Even if the males in your immediate family have hair, you have to look to your ancestors. Some genes can skip generations. Neither my mother or father have much body hair, but my brother and I have an excess of it which comes from our french heritage.
