Hurmat

Asalamualaikum
Respected mufti saab
I would like to know :

1) For hurmat al musaharah to take place does there have to be inclination of intimacy as well as an erection in the private?

2) This is from jamiat Kzn
Is this correct?
Hurmatul Musaharah only takes place if when there is physical contact with genuine lust at the time of touching.

In the case of a male this is determined by the following:

If erection occurs in a male when physical contact is made or if erection increases when erection had already occurred prior to physical contact. If erection does not occur in a male due to health reasons or old age, then if lust occurs in the males heart at the time of physical contact. (Raddul Muhtar 4/107)

Jazakallah
