Shomer/Shalom, G-d/Gosh

Question

Kavod HaRav- I'm not saying this to argue with the shulchan aruch or to find a way out of this, at all- but if telling my brothers that we can't hug or touch at all will bring about real family problems, which no doubt about it- it will, is it worth it to take away some shalom bayit to not touch my brother?? I know it sounds like a cop-out, but I sincerely am wondering if it's worth it... Also, is there anything wrong with saying "Oh my G-d" as opposed to "Oh my Gosh"? Thank you!!
