23M and 22F sort of small issue

I was at my gfs place , I was turned on so tried to initiate sexual interaction but she was sick. So I decided to go inside the room and m***sturbate. She proceeded to come in and crash out and tell me what r u doing don’t do that so I said r u Fr then I told her aight leave I’ll be right out and stopped and came out and sat with her . She thinks it’s a big deal , I don’t she thinks it’s not something to move past i do ?
