I just feel relaxed, sometimes tired. :) Depends on my mood, but masturbation is very healthy and natural in my view, especially for women who have more complex pleasure points. We need to understand our bodies, and this enables us to do it. I don't think it has ever had any impact on me relating sexually to a man, even after periods of celibacy. Because being with a caring human cannot compare to an electronic device...a real, loving and passionate man is always better. :))
