Lol your mom made you get rid of that? When my bro saw my boobie gifs he told my mom and my mom's like "I don't care just don't let me see you jacking off." lol anyway, to fix it u might want to get a soft brush, maybe blur or eraser and go around the jagged lines and click along the edges to soften it up. Or u can add a layer of gaussian blur and add a layer mask and brush the render
