First Married Date

I have been married to my husband and best friend for 11 years. We both enjoy sex in ways I could never have imagined before him. We got into threesomes 3 years ago with both men and women. A few months ago we invited a guy we have known for a good long time to join us. This man is very attractive and very well endowed. He has been to our home for several threesomes and a couple of foursomes when another woman was there. While he has had sex with the other woman at our home,he always spends more time with me while my husband spends more time with her. NOW comes the question I am concerned about. He wants me to spend the weekend with him as a couple. My husband and I have discussed it and he said he would be okay with it and would spend the weekend with the other woman.While I am a bit excited about being out with him I am also scared of stepping into this new territory. I don't love him (I do love my husband) but the thought really turns me on. Any thoughts on this subject? Anyone been there?
