Re: So what if I do not want to have kids?
Yeah, my mother is well-meaning and so when she pressures me, I sometimes have to remind her I am not a baby factory, and so she has backed off.
I think my MIL is afraid to ask me for risk of feeling like she is pressuring me, so instead sends my SIL to investigate. I give vague answers.
As for the "punishment" thing, I do feel that there is a certain degree of guilt associated with being a happily married couple and engaging in "carnal delights." People feel they have an excuse for such behavior if they are also having kids.
