Just realized I’m into MFM dynamics - advice on exploring this further

I’ve recently realized how much MFM fantasies turn me on. My wife was a virgin before me, and the thought of her getting to explore something new while I’m there really excites me. It’s a mix of wanting her to feel fulfilled and also being turned on by the idea of us opening that door together.

The thought of seeing her let go and explore a side of herself she’s never shared before feels both thrilling and incredibly hot. She’s hinted in the past about wishing she’d explored more in college before we met, which makes me wonder if she might actually be interested.

I’d especially love to hear from people who’ve been in a similar situation — one partner had more experience, and you decided to explore something like this together. How did you bring it up, and what helped it go smoothly?
