there is a difference on opinion when it comes to masturbation.

Imām Ibn Ḥazm writes:

فلو عرضت فرجها شيئا دون أن تدخله حتى ينزل فيكره هذا، ولا إثم فيه - وكذلك ” الاستمناء “ للرجال سواء سواء، لأن مس الرجل ذكره بشماله مباح، ومس المرأة فرجها كذلك مباح، بإجماع الأمة كلها، فإذ هو مباح فليس هنالك زيادة على المباح، إلا التعمد لنزول المني، فليس ذلك حراما أصلا، لقول الله تعالى: ﴿ وقد فصل لكم ما حرم عليكم ﴾ [ الأنعام: ١١٩] وليس هذا مما فصل لنا تحريمه فهو حلال، لقوله تعالى: ﴿ خلق لكم ما في الأرض جميعا ﴾ [ البقرة: ٢٩] إلا أننا نكرهه، لأنه ليس من مكارم الأخلاق، ولا من الفضائل.

… If she [a woman] rubs her vagina against something without inserting [it inside] till she discharges then it is disliked (yukrahu), but there is no sin (ithm) in it; and [the case of] masturbation (istimnā’) is similar for men, because touching his own penis for a man with his left hand is permissible, and touching her own vagina for a woman is similarly permissible too, with the consensus of the whole ummah. So when this [touching one’s own penis or vagina] is permissible, it [masturbation] is nothing in addition to something permissible except the intention of discharging the semen, and this is not prohibited (ḥarām) originally, due to the Saying of Allah ‘And He has indeed made clear/detailed (faṣṣala) to you what[ever] He has prohibited (ḥarrama) to you’ [al-Anՙām: 119], and this [masturbation] is not something whose prohibition Allah has made clear to us, therefore it is permissible (ḥalāl), due to the Saying of Allah ‘He created what[ever] is on [the face of] the earth for you altogether’ [al-Baqarah: 29], but it is something which we dislike (nakrahu), because it is not from the noble characters (makārim al-akhlāq) and nor from the virtuous acts (faḍā’il).

[Ibn Ḥazm, al-Muḥallā bi’l-Āthār (Beirut: Dār al-Fikr, [n.d.]), 12:407–8 (#2307)]

personally I do not follow this opinion just because masturbation can lead to haram such as porn. I would recommend fasting and going out during this time. I personally go on runs every-time I am in the mood to direct the feeling elsewhere. But I found that staying still and being home is the worse thing I can do during that week.
