Cuddle/hug/hold wife while fasting;long hair and ghusal everyday

1.can i cuddle/hold/hug my wife in bed when sleeping whilst fasting? i do know that sex will break ones fast but that was not intended.

2. my wife has long hair, does she have to wash it everyday if we have intercourse everyday or can she wash just the tips of her hair? because washing her hair everyday is becoming difficult for her and will lead to depriving me.
