You're so fixated on numbers and definitions your brain rivals the smooth, water filled brain of Onision.
I'm gonna dumb it down for you real easy. Lowering age of consent won't make anyone want to get married more. Nothing except giving some kind of bonus to married couples like some kind of monetary benefit will make people want to get married more. You can't teach people to fall in love, there's no marriage education class that would ever be able to do that and make children decide to be pure little virgins until they find their one true love and stroll down the aisle like a fairy tale.
Sex ed is purely to let children know how not to fuck up because everyone knows kids will experiment. You have to have sex ed because you can't rely on every family to teach their children anything. Sex ed also includes teaching girls how to look after themselves on their period btw, which stops them getting toxic shock syndrome when they leave a tampon in for 2 days. If you think sex ed encourages sex you obviously haven't had a class where a teacher pulls out an HD image of a wart covered vagina or some syphilitic cocks. That's enough to convince anyone to use protection.
Oh, and lowering the age of consent will only allow older people to legally molest kids, because like it or not a child is more than just an age range. I mean young me was convinced that when you turned 25 you magically just became an adult. There's no arbitrary age that transforms you into an adult, physical maturity means nothing when it comes to the mental effects sexually abusing someone has on them.
No amount of law changes or policies will get someone to fuck you. I'm sorry you're a lonely incel but sometimes we just have to accept these things in life. Just buy yourself a loli onahole and imagine it's a 13 year old for you to dick.
