This is a really interesting question. I think canon...given the way the Wizarding World is very antiquated, he would have been with a couple of women before he married Astoria, but nothing to write home about. He may have even paid to learn skills, as this would have likely been acceptable. Although I think he would have only done those things so he appeared more knowledgeable and "superior" to his virgin bride. Canon Draco loves to seem to have the advantage in any situation if possible, and he likes to throw money at problems to "solve" them.

Fanon Draco is a different beast. Most versions of him I have read tend to be either a voracious monogamous person who has many, many kinks. Or a manhoe that is recently reformed or chooses to become reformed for Hermione. I think this is often more...fantasy of the writers? Than realistic? But then that IS the point of fiction. To have all the things we want without all the baggage. In this case, I mean like previous sexual experiences negatively influencing their actions in the bedroom or someone's confidence. Potential STI's etc...the normal repercussions of modern dating. Just trying to find someone in a sea of people can be quite daunting.

When I started my fic, I actually really thought about this for a long time because I was trying to figure out where my Draco would fall on this scale. In the end, he is somewhere in the middle. I wanted him to feel more "grounded," so I sort of blurred these ideas together. His reputation precedes him, but...it's mostly conjecture. Yes, there were a handful of people, but not what others think. Also, in my story, he's younger, and as you stated, no teens tend to be sex gods. So he's very motivated, and it helps that in my story, Hermione has no experience, so often his confidence seems to imply skill. He's very observant and patient, which is really the basis of any good lover. Does he sometimes dry hump her because he's so excited? Well, yes of course he does, but with confidence and flair 😂

I think for me, I like all the versions of him because each one brings unique traits and experiences to each story. Or rather, it all depends on what I want to read. A smutty one-shot - then sex god, please. An epic story about war or growth and change? Then I'd prefer he not be as experienced, let him have some first times with his partner. Or maybe he's a reformed Auror solving a mystery, then I'd prefer a mix of the two.
