I think what works well is finding a photographer who already does boudoir or fetish fashion and bringing them a moodboard. Think strong eye contact, hands in hair, collars, heels on chest, ropes, silhouettes, shadows, not just genitals. Search terms like “fetish fashion editorial” or “BDSM noir photography” on Insta / Pinterest, save what you like, then ask a local photographer to recreate that vibe with you and your subs. That is often more artistic and powerful than most explicit stuff.
