You need to find someone who you have both love and adoration for and sexual chemistry with who emotionally stirs you as well before you can claim that masturbation is superior for orgasms.

I once practiced semen retention for five days only to finally orgasm while masturbating while simultaneously being dominated by my lover and that one was pretty high ranking, to be honest, but it doesn't really touch when an orgasm goes through your whole body into your legs or what have you and it's making you convulse still some 20 seconds later after having a full encounter with your true love and you are saying "oh fuck, oh shit!"

I hope this is OK to describe considering what this thread is about and the claims being made.
