So I'm a big big fan of Rebbe Nachman of Breslov whose many wise quotes and anecdote I have often appreciated in books like This is Real and You are Not Prepared or in songs like Kol HaOlam Kulo. However, apparently, he also both believed it was aveira to ejaculate outside of a pussy but also that it's okay to do so so long as you recite psalms 16, 32, 41, 42, 59, 77, 90, 105, 137, and then 150 in that order; which then makes it okay that you made yourself cum. The line "most Breslover Hasidim try to say the Tikkun HaKlali daily" is amazing to me immediately following this. Beslover Hasidim definitely jack it on the reg.
