I have been introduced to a boy for marriage through my family, both our families are happy and the boy really likes me too, our feelings are mutual.

However whenever we talk – obviously due to us liking eachother the conversation is very friendly and sweet – due to this, naturally I can tell that my body reacts in a different manner that I haven’t previously noticed. Does this mean I have to do ghusl? Our conversations are not sexual at all yet I’m confused why my body reacts this way hence I’m concerned which fatwa would fit in here.

If the reaction of your body is not sexual excitement then there is nothing you need to do; however, it is not permissible to have conversations that arouse such feelings with someone who is not yet your husband
