Okay so I JUST read this interview where Cumberbatch described how Sherlock would truly be in bed and I definitely want to do a rp like this. This was his description in the interview:
Things started off simply enough, with Cumberbatch describing how he would test latex, run an experiment on "durability and length," take vitamins, shave and watch porn. But then came the boom. (Get ready to think about violinists in a different way.)
"And then I would be devastating," said Cumberbatch. "I’d know exactly how to please a woman, I’d know exactly where to put my fingers, where to put my tongue, where to put my — his, I should say — his fingers, his tongue. Think about violinists, think about what they can do with their fingers."
The actor picked up steam. "And I’d know exactly how to get that person into it, and get pleasure out of making that person feel pleasure to the point that I probably wouldn’t even have to enter."
"But when I did it would be explosive," he added.
So, I wanna do a story between Sherlock and an OC where there is something about my character that draws Sherlock to him. She's innocent, beautiful and seductive but without realizing it and that's what makes her so intriguing to him. So, now he decides to take action and see what it will take to seduce her and makes her his.
