I never read smut, but I still blush furiously when I read fluff, don't understand it.<<<< Don't really read smut but Gosh fluff makes me blush and squeal like I literally get the biggest smile ever ! Like gosh damm it WHY!
That's how I picture johnlock. Not loads of sex, but snuggling and secret kisses and feelings and just sleepin together-> Same. I feel like being in an relationship with Sherlock wouldn't require a lot of Sex or PDA.
