i don't think i'm qualified to answer this question HAFAHJFGJ but when i do write smut i think the main thing i try to focus on isn't the actual sexual mechanics of the scene but rather the mindset of the characters in the scene. like what is their relationship to each other, is this their first time, are they nervous/excited etc. i consider how they interact with each other, and make sure that that dynamic translates over to the bedroom. i think intention is really important (unless it's simply a one off pwp scene) like what is the point of this smut in the larger scope of the fic, is it even needed, and if it is what will this tell us about the characters and how will them interacting in this intimate way affect their relationship from then on. so when you consider all of this pretentious stuff i think the smut will come easier...but in general unless you're a very horny person i feel like smut will always be hard to write 😭 it's a lot of body parts to keep track of and a lot of steps to go through, but if you prioritize character over everything else you will know intuitively how these characters would fuck. for lack of a classier term. sorry if this doesn't help i'm still trying to figure out the secret ingredient to good smut myself but at the end of the day it's all down to preference and what you like! just go with the flow and don't take it too seriously~~~
