So, the characters:
Husband and I have been together for 13 years, married last year and finally moved in together after. Both of us are straight. Our relationship has been very happy. This is our first disagreement this year.
Best Friend (BF) and I have been friends for 12 years. Eight years ago, she moved to another state for school and stayed there. We visit each other every year or plan an annual trip, sometimes with other girls from our friend group. We talk at least once every week for an hour or two, catching up. She was my maid of honor, and we have been there for each other through thick and thin. She is bisexual and had one girlfriend in college; all her partners after were straight men.
All of us went to college together. They've known each other from the beginning. We've hung out together. She's visited our place multiple times. They text each other happy birthday.
So, she and I are going on a week-long trip together on Saturday. This has been planned for months. Last night, we were on the phone talking about what to pack. She asked "Should I bring my sex toy? Are you going to bring yours?" I replied, no, because I don't have any I use anymore. She joked, ah married life! We moved onto other topics.
Now my husband overhears and gets upset, holding it in til we get to bed. "Are you going to tell me why you guys bring sex toys on a get together??" From talking to him, his concerns are that we are using it together and that it's weird to bring a toy on a trip, and people only use them at home. I replied 1) it's weird for me to even think about using it with my friend and our friendship is not like that, and 2) I don't understand what's weird about this situation; we have separate rooms in our airbnb as usual and that's her business. She can do whatever she needs/wants, and it doesn't involve me.
He turned away saying it's weird and hasn't talked to me since. To me, he seems jealous and has a misconception about masturbation but I don't know if this is just how people feel?? Can you help me understand how he is feeling and how to approach this situation to explain to him that it's not weird to me and he has nothing to worry about?
