Is edging a sin?

Question:

Hello,

I would like to ask if edging is a sin? I know it would be if you were involved with anyone else and also would be if you were involved in porn or lust. But what about by yourself without either of these?

Answer:

“Edging” is the practice of stimulating yourself to get close to ejaculating but then stopping before orgasm is reached.

The problem is that instead of masturbating because there is a physical need to relieve the building sexual pressure, there is a chasing after the pleasure. While there is nothing technically wrong, seeking out pleasure for pleasure’s sake leaves you open to many temptations. See Is pleasure a sin?
