I think this is quite common for some guys - I've certainly read others here mentioning the same thing.

My guess is that as the hairs grow longer, they will start to come down on their own due to gravity. The good news is that without the natural tendency for them to grow straight down, they won't be in your mouth as soon! I would try to train them to the sides rather than press them down. There might be some useful discussion in the 'taming the wild stache' thread. Follow the link to it in my signature.

Your beard has come in very nicely BTW. Nice coverage and density.
