HI CherryDropz88 - in my opinion this is excessive. As you said this is impacting your life in a negative way and this is a good indicator, it's reached an unhealthy level. Masturbation in itself is normal and fine. I don't think you should feel embarrassed - you could be addicted or I saw once on Oprah, there's a condition where a woman can be super sensitive to stimulation - where she must relieve herself. You said you fantasize about your therapist - has this increase started recently along with feelings for your therapist or have you been like this for a while?
