>>33187203Well that's gonna come down to what sort of lewd you're trying to pull off there son. If you're going for explicit lewd (heavy detail) then you're going to have to learn how to weave the tale in a such a way that it doesn't come off as gross - and that means you're going to have to read a lot of explicit stuff. Good and bad alike, because they teach you what you like, what to look for, and what others like.
Alternatively, if you're trying to write lewd that's more subdued and relies on implication and titillation, then you're going to...have to do the exact same thing. Consume good and bad works to get an understanding of what works and what doesn't.
Writing either kind of lewd requires practice and awareness of your prose, so don't be discouraged if your first few attempts are less than stellar or even outright cringe - if you practice you'll eventually get it.
You'll also want to make sure you're writing appropriate reactions, actions, emotions, etc. for the subjects. Sex isn't always this one-hundred percent serious affair where both sides are just straight fucking with no communication outside of announcements of imminent orgasm. Sometimes you goof up. Or they do. Or one of you falls off the bed. Or knees the other in the eye.
Don't ask. And sometimes it really is just wild, poorly constrained lust.
