My new girlfriend likes to take sexy photos of herself on her Instax mini and that really impressed me. Her photos are really well composed and sexy, and I’ve been curious to get into boudoir photography myself. I’d like to take some sexy photos of myself (I’m a guy in my 20’s) and I could really use some tips on posing, lighting, composition, accessories, and whatnot. Especially anything to help me take photos that are “tasteful”, whatever that means to you. I’m quite new to portraiture and so I have very little experience to go off of. I have an Instax Wide. Any tips, thoughts, and comments are welcome. As well as recommendations for learning resources, like articles, videos, and the like

Additional info: - my girlfriend and I are keen to take boudoir photos of ourselves together in a photo shoot, on both regular film (mostly B&W 35mm) and instant film, as well as digital, so any tips and thoughts for posing and setting up our apartments for a good shoot, like lighting, accessories, and whatnot is also very much welcome - I intend to shoot my self portraits mostly with B&W instax wide film - I have an instax printer and a Fuji XT2 which I’m debating on using as well
