Does the emission of semen—without touching the penis—after conversing with one's wife via phone or internet affect an oath or a conditional divorce based on not masturbating?

If a person swears to abstain from unlawful masturbation, he does not break his oath by masturbating through talking to his wife without using his hand. It is advised to avoid swearing by divorce, and it is also cautioned that using oaths to compel oneself to abandon sins is not a sound approach.
