First of all, congratulations on finding the love you've been looking for. I'm glad you have a loving and secure relationship. That is the first step in considering swinging.
Everything you say sounds completely normal. My husband and I are newbies too. And I go thru the same feelings. Spend some time reading thru the New Swingers forum. And check out the archived threads too. I found a great deal of information that helped me out in the archives.
The one thing people here will tell you is take the time to talk things out until you're both comfortable. Talk, talk, talk, and more talk. If everything doesn't feel right for both of you, don't do it. There are people here who took several years to start swinging. They said they felt like they talked the subject of swinging to death. But it was worth the wait. And they'll tell you that swinging is not for everyone either.
Be patient and take your time. It's hard to find a couple where there's attraction from all parties.
Read thru the board. Both of you, together. And ask questions. There is so much experience on this board that can be of benefit to you.
Take care and let us know how things are going for you.
