>I think that's more because people don't want to teach children about sex
Come on now. It's hard to find anything more immediately exciting and alluring than sex, especially for teenagers. The biological imperatives and inclinations are too strong regarding sex for virtually everyone, compared to anything related to gambling. And OP is absolutely right that the barrier to entry is a great deterrent in the case of gambling, as well. Just based on that alone, easy-access, sex-related stuff is always going to have a potentially greater effect on almost anyone, regardless of their previous knowledge about it or warnings received by other people during their childhood.
>people do demonstrate what gambling is early on
Talk about going out on a limb. What are you basing this affirmation on? I don't see any parents lending any word of advice to their children about gambling-like activities, in any case, as most of them indulge in those themselves, let alone their own kids.
