LL is overrated and shouldn't even be considered as a "solution". Unless you have an unnaturally long arms/torso to balance the leg extension, you will look like a disproportionate clown freak when you take your cloth off and she sees those long ass legs with a torso of a manlet kid. Even if you manage to get her in bed she'll freak the fuck out when she sees where all your tallness comes from.
Even with clothes on, people will notice that there's something odd about you and you'll get called out and embarrassed.
And then of course the price tag and even worse a one year "time off" recovery, who hell can afford to be off work for a whole year while having to pay ridiculous amount of money for the surgery of this magnitude. Sorry but I didn't win a lottery or inherit a jack shit from my ancestors.
And if you think breaking your legs won't have any side effects on your health, then just lol.
