You have a walrus stache growing now. I can see the curling. It is a great mustache style. Many guys here sport it. I guess it is a personal preference in terms of what you are comfortable with. Some will trim it if the hairs are getting into the mouth. But, only a little that over hang. Some guys just move the stache to the side when they eat. Contact Abn82(Keith) about using hairspray. He uses that technique and it works great for keeping the stache in place at longer lengths. You can also try wax if you want to style it to the side more. Firehouse wax is brand that I have used and it works great. Another product is hair glue called got2b. Or keep it natural without products. I tend to lean toward no products personally. I don't like the feel of the stiffness that comes with using these products. I tend to trim slightly once in awhile the hairs that go into my mouth but leave the rest of the stache alone. If you don't know, it is best to experiment.
