Marriage with no intimacy.

My husband is a very good man. Sadly, we rarely have any intimacy, and even when I initiate, it has led to rejection. This has really damaged my self esteem and confidence. I know I need to bring this conversation up to him.

I would like some advice on how a man would like this topic addressed and the best words to say, so I don't cause upset. I would like to take a soft and kind approach without causing hurt.

Please advise.
