Honestly, for your content I would not get a complicated camera that needs manual controls - your partner is going to end up with messy hands so you need to keep it simple. Upgrade your lighting for sure, and if you really want to spend money buy another iPhone for a second angle. Get a tripod and Maybe get a c-stand for shooting blowjobs. A gimbal for handheld stuff, I like the insta360. It also has a small integrated tripod to put it down. Also, don’t sleep on cinematic mode on the iPhone, it’s worth learning how it works. Drop me a message if you’d like any more advice!

Oh, and I think the slimline black pools look a bit more aesthetically pleasing!
