Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.

Massage made by a male for a male is permissible provided that there is no touching of areas that must be covered. This is based on the hadith of of Abu Al-`Aliyah who reported:

Ibn Ziyad delayed the prayer. `Abdullah b. Samit came to me and I placed a chair for him and he sat in it and I made a mention of what Ibn Ziyad had done. He bit his lips (as a sign of extreme anger and annoyance) and struck at my thigh and said: I asked Abu Dharr as you have asked me, and he struck my thigh just as I have struck your thigh, and said: I asked the Messenger of Allah (peace be upon him) as you have asked me and he struck my thigh just as I have struck your thigh, and he (the Prophet) said: Observe prayer at its prescribed time, and if you can say prayer along with them. Do so, and do not say.” I have observed prayer and so I shall not pray.” (Muslim)

Furthermore, it has been narrated on the authority of Anas that the Messenger of Allah (peace be upon him) raided Khaibar. One morning we offered prayers in the darkness of early dawn (near Khaibar). Then the Messenger of Allah (peace be upon him) mounted (his horse). Abu Talha mounted his and I mounted behind Abu Talha on the same horse. The Prophet of Allah (peace be upon him) rode through the streets of Khaibar and (I rode so close to him) that my knee touched the thigh of the Prophet of Allah (peace be upon him). (Al-Bukhari)

Scholars concluded that it is permissible to touch other men’s thighs while having a barrier.

It is prohibited to be sexually aroused by being touched by a male. In your case, neither you nor the person making massage intended or even took steps to sexually arouse you. Therefore, you are not sinful in this case. May Allah forgive all your sins.

Allah Almighty knows best.
