It can usually be tough to tell the exact gender of a bearded dragon when they are younger but seeing that your dragon is 2 years old you should be able to tell. Usually you can tell if you look above the vent, like in your picture. Males will usually have two separated bulges when females will have one. I will provide a good link that shows nicely taken pictures of a male and female. Females also tend to have a more thin shaped head, like an arrow. Males will usually have a larger more broad head. Also! Males will usually have larger more prominent femoral spores that form a type of line along the bottom of the hind legs. Females will have them too but they wont be very large. It does seem that you have a female but I cannot be the one to determine this for sure. Here is a good link that shows examples: http://beardies.dreamwidth.org/2476.html
I can answer every question towards the bearded dragon except for questions that deal with sickness and disease. I can answer questions on heating and UV rays, the questions pertaining to food, habitat, bedding, breeding, egg/hatchling care, nature, and attitude are my best. Last, I cannot help you with at home sickness meds, always find a vet within your area. I can answer questions regarding body language and movement. I will try to help you to the best of my ability.
I have owned bearded dragons for over seven years and have been a breeder for two years. Caring and raising bearded dragons has been a great experience in my life and will continue to play a big role throughout my life.
