But if you want to my advice is don't make it fast and make it intimate and consent. For example this author really made it stunning and with so much passion. Carved_potato I'd the author.
Your story is so great you can be a writer if you want to and keep it up and hope you don't cancel it but If you want to do okay and rest if you need and it's fine that you won't write smut if your uncomfortable just make it slow burn. It's more fun that way , keeps the readers on edge.
