Boudoir photos!?

Okay so I want to do something a little more special for Valentine’s Day! My boyfriend and I have been TTC for 20 months now. It’s not been an easy process.... I’d love to take some photos for him and order it in a book for him. I can’t afford to get them done professionally right now, so I will make do with what I’ve got! I do have a nice camera and a good iPhone also lol. Any tips/tricks? Poses, lighting, good edit tips, angles etc? Please feel free to drop your own photos for inspiration!!!
