A man's hand touched my arm over my clothes. Now I cannot determine whether I felt his body heat or not. I just remember feeling something in my vagina. It felt like something might have come out of my vagina. Did it cause hurmat musahara?

The rulings of Hurmat Musaharah (incest) are delicate and intricate.
According to the Hanafi Mathhab, Hurmat Musaharah will be established between a man and a woman when one of them touches or kisses the other (without the barrier of a thick cloth) with Shahwat (lust).
It is also necessary for the establishment of Hurmat Musaharah that the Shahwah is experienced at the exact time of touching.
Taking this into consideration in the above situation, Hurmat Musaharah has not occurred.
