My short answer here because I already spent around half an hour to explain it on QQ.
Indulge = "become involved in (an activity, typically one that is undesirable or disapproved of)."
Well, because it's natural people (not only males) to prefer younger than old ones for mating + it's not forbidden (illegal), the forum doesn't "indulge", it just allows everything which is legal.
When I translated the Chinese criminal law (years ago) it was stipulated there that what's not forbidden in the law is legal, allowed. Logical and right. Isn't it?
So, if really most of the Chinese disapprove that teenagers (14+) may have love and/or sexual experience, then it's the Chinese society problem or, let's call it, cultural side. Most of us (luckily) are not living in China (Xina) anymore, so we really can't care less what some or most Chinese like/dislike when it comes what we like or dislike.
You don't like teens? Good to know. Then you will ascend faster. But you are you, we are we. We, maybe, like every good and beautiful woman, we are not ageism followers and we think that you prefer your age, aunts or grandmothers (no matter which) is your 100% free choice! Enjoy it and we enjoy ours too. That's what's the freedom about: you, he, she, all of us to like what we want to like (if it's not forbidden). Well, it's even not forbidden in China, as far as you are not a “炼铜”.
Don't worry too much and focus on your gymmaxx and edumaxx + moneymaxx. Once you geomaxx out of Xi-na (Xina) you are almost safe and successful.
Good luck!
