Fantasize about someone you've never been with.
This sparks the creative centers in your brain instead of going to the visual centers with porn or the memory centers with past experiences. Play the entire courtship out in your mind and be luxuriant in your reverie. You can simply think about it, write a short story, make a comic, talk about it with a lover or just enjoy the sensual movie in your mind while you self pleasure. Draw it out and tune into all the senses: taste, smell, sight, sound and of course touch.
Feel free to DM me with your experiences or any questions you have. Enjoy!
