Chastity, ergh!
Valuing sexual innocence (and by converse, rebelling teens valuing sexual experience) is just a relic. Sex should be something people do, not something they are.
Having sex doesnt mean you lose anything substantial, and to be blunt, its just not that magically special and its something people can learn to get better at.
So, if you really want to impress your partner on your wedding night, then present them with some experience and dont glorify the lack of it.
I mean, apply the same attitude to any other aspect of life and you'll soon see the silliness.
"Dude! Its just a wargame, Warhammer 40k is just not that important!"
"Not important to you maybe, but im saving myself for someone special"
"But you dont know the rules, dont you think its gonna be a pretty rubbish game when you finally get round to it?"
"No of course not, because I will gain a mystical bond with my partner that will garentee a great game"
"So who exactly are you waiting for?"
"My soul mate obviously, if I have my first game with them then somehow that will give our relationship extra meaning"
"Yeah but who?"
"I was thinking a Dark Eldar player..."
"... you really know nothing about 40k do you?"
"Thats the point, but im sure my mystical bond will enable me to work out what im meant to do with these dice things for instance..."
