Caught Up in My Own Fantasies

I've been struggling with something I'm not sure how to handle lately. It started when I was working on a sculpture of a naked woman, trying to capture every curve and angle just right. The process is incredibly sensual, the way the clay molds under my hands, the pressure of each touch, it’s almost like touching her in real life. As I worked, my mind wandered into more intimate territory than usual. Before long, I found myself getting turned on, imagining she was alive and responsive beneath my fingertips. My fantasies became so vivid that one night, while I was alone in the studio working late, I couldn't help but let out a moan as I touched myself. I went into this intense roleplay where I'm sculpting her body and experiencing every moment of it through her skin, feeling her muscles tense up under my hands when I pinch a hip bone or run my fingers along the soft valley between her breasts. It’s like a physical, intimate dance with another person. My heart races as I picture her reactions to each touch, her breathing changing in time with mine. The climax was overwhelming, but now that it's over, I’m left wondering if this is healthy or if there’s something wrong with me for getting so caught up in my art like this. Am I just being too imaginative? Is it normal to fantasize about a sculpture as if it were real? Or should I see a therapist before it consumes more of my life?
