[/INST] Degree understand your concerns went through your details. You are masturbating for the last 10 years. That is not a problem at all. Masturbation in moderation is healthy and is a stress buster. Don't worry. Regarding the current sexual experience with your girlfriend, it could be due to simple performance anxiety because you may be doing sex as a starter. Don't worry. Without getting anxious and worried, carry on. Your problem should be solved. Or you may consult a psychologist for counseling.
