Ques to DINK couple/husband - Are you the only SON (single child or sisters) in family?

Sharing the context for this question - Indian society does not accept (easily), and it may pressure families with only ONE SON (single child or one among sisters) , because he bears the onus of continuing the lineage.

Are there any couples (or you know of someone), who chose to be different?

P.S. The question is only for serious DINK couples who are not considering kids. You are not DINK, if you "may plan in the future" or "let's see how it goes"
