intimacy is very different culturally. but generally it is any physical interaction with your partner.

to give you an example, i have heard from an indian friend that they would not touch their husband in front of their kids. no holding hands, hugging or kissing of any kind. i don't know if that is common in indian culture. i am not trying to generalize.

the point that matters is that i feel very restrained in how i act when our housekeeper is present.
