Hurtmat-e-musaahara
Q: I would like to know for hurtmat-e-musaahara to take place for a male he must have an erection, so how does a female know if she committed hurmat-e-musaahara? Also if a person has no desire for there father in-law at all, they just know the rule of hurmat-e-musaahara and due to waswasaa when shaking his hands thinks "I dont want to touch his hands, now I am touching his hand lustfully" and they have a funny feeling. So they don't really know if they actually touched it lustfully or not But they really don't want to touch his hand. They just shaking it because the father in-law gives out his hand to shake. What is the ruling on this? And how can they control this?
