I'm posting here because I need godly advice.

My husband and a separated a while back, but have choose to remain intimate. Neither one of us are interested in divorce, we just live separately and don't share finances. Our relationship is good, we just aren't "together". I see no problem with this because

1. I can't control his actions

2. We're still married

3. I meant my vows

4. Scriptures.

Here's the problem.

He wants to be more creative in the bedroom, and I am trying to figure out where/if there is a line that shouldn't be crossed. How creative is still ok, assuming consent from both parties?
