If you convince me,not based on experience,but on goodness that it is good to have sex prior to marriage,i will consent.
You have to convince me and I must believe you that you do not want it for your pleasure but for the goodness. On the other hand if you really want to sex with me why would you not have marriage first. You do not have to be believer you do not have to be Catholic but if you really love me you would consent to it the way I believe is right. You can be sure of that waiting for what is pleasurable until marriage isn’t from my point of view anything bad.
