Re: i know this is a embrassing questionn but i need help!
Do not talk to him before the wedding about this. And even after the event, try to limit what you say it and how you say it until he gets to know you better. Cultural differences bhi koi cheez hotay hain.
seriously though, she's marrying him! for better or worse, they're going to spend their lives together. there are ways of discussing birth control and babies without it being lewd and seeming like she's "fast". it can even be as simple as, "when do you think you would like to have kids? because i would love to in the future, in a few years, but i'm not ready for them right now and i was wondering what you think about that?". it doesn't have to be all "if you dont wear a condom, you're an ass and we're never going to get jiggy with it ever".
ideally, the whole kids talk should have taken place before they decided to get married to avoid this whole mess in the first place-- even if it was just to get a sense of what the other person's expectations are.
