If I had a partner, I would not want spontaneous sex. My idea of sex preparation would be, 1) brush my teeth at least two hours beforehand, 2) put fresh clean sheets on the intimacy bed, 3) have a shower and put on clean boxer shorts, 4) girlfriend has a shower and puts on say a clean satin spaghetti strap top and satin boxer shorts (or in opposite order), and whoever has a shower first goes to the intimacy bed.

I would want to have the room dimly lit (no candles, mind you, just lava lamps). I would say to her, "Let's switch our phones off, not worry about what's on the internet and just take in the wonderlands that are each other's bodies." I'd also want to put the air-conditioner on around 14 degrees centigrade, so that we could pull the duvet up.

Why I would hope that she'd go for a top and boxer shorts is that a girlfriend and I would need, to be sexually compatible, to be turned on by the same things. And, for me, that would be that she lay in bed with me, and I started kissing her at her hairline, down her forehead down her face and gently nuzzled her neck near her ear with my nose while kissing down her neck. Then go down her neck to her shoulder and kiss an infinity symbol across her chest, then go down and kiss an infinity symbol on her belly.
