Realized I'm attracted to women at 47, married to a man for 22 years. He's supportive. I'm confused.

I keep clocking women at the supermarket. The barista at the place near my office. A neighbour's wife at a school pickup. At 47. After 22 years married to a man I love. The framework of my attention has shifted in a way I didn't think was possible at this age. Last August at a Toronto club my husband was on the other side of the room with someone else. I met her at the bar. We ended up in a corner for almost an hour. First real woman-on-woman experience for me, and it wasn't a "trying it for him" thing, he wasn't even in the room. I can't stop thinking about it. Not just about her specifically, about women in general now. Husband is fine with it. Says he always wondered, which is its own thing to unpack. He'd be happy if I had a girlfriend on the side, happy if I just enjoyed it at parties, honestly more relaxed about it than I am. We've been doing the Toronto downtown soft swap circuit for about six years, three kids, eldest at college. What I'm struggling with is the identity piece. Do I call myself bi now? Bi-curious feels patronising at 47. Lesbian doesn't fit because I love my husband and still want him. Pansexual feels like a younger person's word. The "late-blooming bisexuality" literature exists but it's mostly about women in their 30s discovering it, not 47-year-olds with adult kids. Anyone else gone through this later? Did the label matter to you or was that just a phase of the process?
