>>816753If I understand your problem correctly, you want to convince yourself that you don't like sex or the process of attaining it, just the romantisized version of it in your head?
Try techniques that reduce horniness. I here exercise and cold showers are good. I'm sure if you google stuff about how monks repress sexual urges, you could find more.
If you don't mind me asking, why do you want to do this? Why do you wanna repress your sexual desires?
