Intimacy is not purely physical. It's the act of connecting with someone so deeply that you feel like you can see into their souls.
The most important elements of any relationship are trust and respect. When you trust someone enough to be honest with them, you grow to respect them and yourself. Where there is trust and respect, intimacy resides.
True intimacy is the experience of real acceptance and authentic vulnerability without feeling the need to apologize or fear rejection. The freedom to just be and know it's all good.
