Give Satisfaction

I agree with you that writing smut is a varied thing depending on the author and fandom. Like you, while I have read a range of smut not all of it is to my particular taste.

I find that for me, writing smut depends largely on the canon I am writing in. Sometimes I just don't think I can reproduce their voices sufficiently to write smut in detail so I may be vague or give it a miss entirely. Similar to you, there are also acts I'm not keen on, in my case such as BDSM.

I have however explored various kinks for fiction either for myself or as a gift fic for a friend.

Reading kink memes has expanded my knowledge/ interests I admit! Discovering A/B/O was fascinating considering I already liked mpreg lol.

So yes, it really does vary for me depending on the fandom, what characters and pairings I like and if I am comfortable capturing that in a sexual situation. (So far for example, any smut I have written for J&W has been vague using flowery descriptive language; whilst in Holmesian fandom I'm still finding my comfort zone.)
