Is it normal that i wanna imagine and masturbate on my best friend?
I am a 20 years old University Student.
I am in love with my best friend for about 2 years. At first,I fall for her smile and her childish behaviors. But I never imagine anything dishonest at that time; i never noticed her breast or butts or anything. With time, we get closer and closer and I feel something dishonest in my mind, especially when we were in class or sitting side by side, or when she walks in front of me. I got noticed her butt size and her breast size and the thigh gap between her... and I got to imagine and masturbate on her. So, i feel like I am guilty when I see her outside. Am I normal to imagine her and masturbate... cuz she is my best friend and she trust me as a friend or a brother. Am I guilty and should I continue doing that or not? Please advise me kindly.
Thanks in advance.
