Looking for romance book recs to gently introduce my new boyfriend to… spicier storylines 👀

Hey everyone! I’ve been dating my boyfriend for about a month, and I recently realized that I might be a bit more into the “adventurous” side of romance than he is. He’s a total bookworm, can devour a book in a couple of days and I thought it might be fun to gift him a few reads that are still great stories but with a little extra heat or tension woven in. Ideally something that’s not over the top, but could maybe open the door to some new ideas or conversations between us. Any recommendations for well written books that blend good storytelling with a bit of spice or emotional intensity? Thanks in advance!
