i wouldn't feel comfortable discussing the weather wiht my sister...
I would no more ask a personal question on the internet, than Iwould consider asking a stranger on the street... the medical issues I'm currently dealing with are between me and my doctor -and my ability to google...
Misery may love company but I'd much rather deal with issues professionally than with supposition...
sex questions I don't think are much different - asking if it's normal for a person to want sex only x times a week - who's judging what's normal? is it normal for you and are you ok with it then why ask the question of someone else?
Some of the questions that get asked.. honestly I scratch my head sometimes and wonder if they slept thru health class - or why is a person even having sex if THAT is their question...
Disclaimer: I am probably one of the most outwardly conservative and uptight (outwardly) people on this board - what I do behind closes doors stays behind closed doors
