All of these questions make sense to ask!!!!

I can understand how the person being asked can be offended by these things but as humans we are curious. We are especially curious about things that we see as different or we simply don't understand. That curiosity comes out as questions. We can only hope that by asking questions and receiving answers we increase our understanding. And through understanding comes acceptance. I also think that our lack of understanding and ignorance brings fear and that is why things against the "norm" create such issues. Maybe you shouldn't take offence at the question but understand why it's being asked and take the opportunity to educate the person who asked. Remove the opportunity for something to be seen and be judged as abnormal. 

@gjp except we live in an age where you don't need to offend someone. Asking someone who you know well, or even asking Google. None of these are the same answer per couple anyways. Strangers do not need to know how I have sex or how/if I'll have a child. If someone I know we'll, and have been friends with for a while then whatever, as long as they ask nicely and don't get rude if I don't want to answer. But the key point is strangers vs good friends. Would you tell strangers everything equally to your best friend?

Thanks for this post! I've never asked these questions but I'm still happy to know what to avoid!

Assuming people who live together are a couple just because theirs 2 of them. They could be friends who just want to save money by living together instead of alone.

@k-dizzle, it definitely isn't a choice.
