Maybe I don’t understand what you had written?
You wrote about a drug (it is actually a normal hormone, oxytocin and is released under several circumstances) and said:
the more we are intimate physically, the more it would be become a drug, and the more it would be difficult to abstain until marriage.
And I responded that comparing it to a drug belittles people. I see it (your statement) as bordering on implying, if not outright implying that people become so besotted they are not capable of controlling their sexual urges - which in turn is contradicted in the use of NFP in marriage; they - and in particular men - are not reduced to some drugged up sexual prowler.
I do not know of medical studies which show when oxytocin first starts to be released; the literature I have seen is that it it released during sexual intercourse. At what Point, the literature does not say.
But I have my doubts that it is released by a good night kiss on the front porch. I suspect it is released much further down “the road”.
And even when released, it is by no means uncontrollable.
I do not care to take this conversation down the path of describing various stages of sexual intimacy, nor do I believe that involved physical intimacy prior to marriage is appropriate (we can call it a mortal sin, to keep this conversation back to the issue - a kiss). I don’t believe a kiss is a mortal sin, nor even a venial sin. It is often nothing more than a sign of affection; and seems appropriate to me when a relationship is heading for marriage. More than that - nope.
I don’t see the point of the dating culture
“Dating culture” seems to be something out of the 1990’s and since, likely driven in at least a small part by technology (e.g. dating websites). Back in the 1960’s and 1970’s we dated; which might be not much more than going to a dance together (or meeting there); going to a high school or college sports game, or a movie, or a group “date” of several “couples”. That appears to be old fashioned now; and for what little I see of today’s “culture”, it is not anywhere I would go.
However, dating is a means of meeting people where one can get to know the other person - and sometimes, even have fun (is that still permissible?). Many people still find spouses from school; but if one has not, then one still needs to meet people, and preferably more than one.
I have two daughters, both of whom found their spouse in college. And both engaged in group “dating” until they started to focus on one individual. And both seem happily married.
