Call me feminist if you want but a grown man seriously looking at a 12 year old is a pervert.
Are you trolling? It was already pointed out by Everlast that trad men aren't interested in 12 yr olds (and he was attacked as a pedo). The only exception to this would be if a 12yr old looks 16 due to hitting menarche much earlier than the average women, say ~7, that would roughly put them in the same development level as a normal 16yr old when they are 12. Of course that is an outlier and parents will need to adjust their expectations accordingly.
Also the definition of pervert is
a person whose sɛҳuąƖ behaviour is regarded as abnormal and unacceptable.
Do you think that a man looking at a young teens beauty/youth/charm is the same as looking with lust? Of course you are also making an exaggeration by using a 12y old for you example. Is it abnormal for men to be attracted to teens? Biology and history show that it was normal, it's only considered abnormal and unacceptable by some groups in today's world (there are still plenty of secular people who are fine with an age gap).
I think that most guys prefer late teens to mid teens, at 17 a women has already developed enough to be considered 'finished' while still retaining her youthful charm and appeal, while also in her peak fertility. Also her mental maturity/brain development is basically done, no need for Jєωιѕн propaganda citing "structural brain development" as females have a less rational nature to males and are not the ones who lead. While a 15 yr old might be considered cute/beautiful, she usually does not have the mature womanly charm that a late teen/early 20s has.
So here is a question for people who have tried courting or are already married. Did your trad group/priest recommend or require a certain amount of time for dating/courtship before allowing you to get married? And how long was your marriage prep? And was it mandatory?
Using a hypothetical. If 18 is the ideal age for a women to get married then when should she court? If a trad group requires 5 months minimum for courtship and 12 months for marriage prep, then by the time you are actually married the 18yr old would either be 19, 20 or 21. So in that particular example wouldn't it be more ideal for her to court at 15/16 so when she is actually married she is 17/18/19?
Keep in mind these ages are based on that hypothetical time frames as I do not know what each trad group requires/recommends.
