Need to be seen: Cracks at the corner of the mouth can be caused by several things. Over stretching of the lips, some nutritional deficiencies, and an improper bite relationship are some possible causes. Your dentist would be a logical place to start to try to identify the cause and provide recommendations for you.

Angular chelitis: Angular chelitis(cuts at the corners of the mouth) can have an etiology from bacteria, fungus, a loss in vertical dimension, or iron deficiencies. See your dentist for proper care as soon as possible. Proper diagnosis is key for proper treatment.

Cracks at corner of mouth after oral?

Friction, drying: I assume you mean after oral sex you find cracks in the corners of your mouth. It's not serious, in all likelihood. There is a small chance that you have a sexually transmitted disease on your lips, and that requires treatment. But more likely is that the friction and motion of the sex act, plus perhaps the drying quality of genital secretions on your lips, combine to cause the cracking. Lubricate.

Angular Chelitis: You probably have angular chelitis though generally there is some itching or burning associated with it but not always. One thing that can cause this is eating a lot of acid containing foods like tomatoes or oranges. You might try using Hydrocortisone cream over the counter 4-5 times a day but will most likely need prescritption strength to clear it up. Your dentist is the best person to see.
