Would it be healthy for me to masturbate often (once per day) if i have beta thalassemia minor?

Beta thal minor: Beta thalassemia minor is a hereditary abnormality which usually results in mild, asymptomatic anemia and therefore will not affect any of the normal activities of daily living.

Yes: Beta thalassemia minor (trait) does not cause anemia sufficient enough to lead to loss of ability to perform any task. It will not affect sexual performance.
