Being an orthodox Muslim, I was curious about the relationship between existentialism and sexuality. Kierkegaard was a monk. I read that although abstinence does not have any physiological adverse effects but it produces anxiety, which a failed sexual relationship also causes. But I found a clue in this article that one must face anxiety rather than trying to escape it. Thank you very much.
