I think it's just a cultural thing. In today's culture, sex is everywhere: magazines, TV shows, music, Internet, everything revolves around sex. So when someone says "I'm not interesting in having sex right now", people don't get it anymore. Society made sex into a big deal when, really, who care if you have sex now, after you're married, only to have children, or never? It's a personnal choice, nothing more, nothing less. You want to wait ? Wait. They don't want to wait? Then they should not wait. Unlike the previous generations, we have control over our sexual life, and that's a good thing. It should not become another way of sorting people out into categories. Personnally, I have not waited for marriage nor did I want to because, well, I don't really want to get married and don't see it as a major part of my life for which I should be ready in some kind of spiritual and physical way but if it's something meaningful for you, then I'm ok with that. It does not mean I should do the same, it does not mean my whole life will be transformed by your decision. It's just a personnal choice you made and if some people judge you for that, they should start thinking about how this is going to change their life, and when they realize it won't, they should just stay quiet and talk about something else. I just feel like it's one of these subjects that don't need a whole debate about them because they are just personnal decisions that won't affect anyone but the person who took them. Living in society would be so much easier if people just minded their own business and got interested in what really mattered for the whole community.
