Assalamu Alaykum Sir, what does losing chastity actually means in Quranic terms? What type of acts make person unchaste? Does doing masturbation and watching porn looses girl's chastity? If she never had any sexual relations with any man and if she always maintains distance with every man. I know masturbation & watching porn are grave sins and one should not do it, but I really want to know that will she not be able to marry a chaste man, As she is not a fornicatress (Zani) who only has to  marry a fornicator.
