From the what it is worth department....

I feel Intimacy is the ability to be yourself and express yourself and not be judged nor made to feel less than worthy by your significant other.

OR

Intimacy is to be able to accept your partner for who they are and give to them yourself and they to you without fear of being hurt.

Each can be applied in in a sexual or non-sexual fashion.

Through honest giving of my love I will recieve 10 fold in return.

Just because a person does not love you in the way you want, does not mean they do not love you!
