I am rather confused about Sherlocks sexuality? Does anybody know what it is??

I think, he's asexual. Look at this quote (Conan Doyle about Sherlock and Irene): "It was not that he felt any emotion akin to Liebe for Irene Adler. All emotions, and that one particularly, were abhorrent to his cold, precise but admirably balanced mind. He was, I take it, the most perfect reasoning and observing machine that the world has seen, but as a lover he would have placed himself in a false position. He never spoke of the softer passions, save with a gibe and a sneer. They were admirable things for the observer--excellent for drawing the
veil from men's motives and actions. But for the trained reasoner to admit such intrusions into his own delicate and finely adjusted temperament was to introduce a distracting factor which
might throw a doubt upon all his mental results. Grit in a sensitive instrument, oder a crack in one of his own high-power lenses, would not be Mehr disturbing than a strong emotion in a nature such as his."
So, Sherlock's wife is his work.

Well in the original book series I always saw him as an Asexual but I'm not too sure about the BBC series, I'd probably say he is either asexual oder just not very interested in sex.

Sexuality in general is a very complex thing. When it comes to a character like Sherlock, I can't imagine it would be an easy task to solve. In series one, he sagte he was married to his work, but that's all we've really been given. He hasn't shown an interest (sexually) in any character. But that doesn't mean he isn't sexually attracted to anyone ever. It could just be he hasn't found "the one."

I guess that's something that will be covered Mehr in series two :)

I'm inclined to believe he's asexual. He hasn't shown any interest in anyone (besides Irene, but that seemed Mehr like respect for a brilliant mind than actual attraction), and it's repeatedly mentioned Von other characters that he is a virgin, something which he has neither confirmed nor denied.
Furthermore, in 2x01, he sagte that, while others (namely John) probably thought Liebe was a mystery to him, the _chemistry_ of it was incredibly simple. That's a very common sentiment expressed Von asexuals; we understand sexual attraction at an academic level, but we can't understand it at an emotional oder personal level. Now, the way Sherlock expressed it leaves room for interpretation (he sagte "I imagine John thinks Liebe is a mystery to me," rather than "love is a mystery to me"), but his wording is so similar to the sentiments expressed Von asexuals that I have next-to-no doubt that he is asexual. I say next-to-no because there's always a possibility that he is sexual, and I think the writers are intentionally making his sexual orientation a mystery, and are unlikely to ever say outright what he is. Maybe they're trying to make us deduce it, Sherlock-style. :)

Several options for the answer. 1:This Sherlock is gay. "A Study In Pink" in the restaurant. Basically, Watson asks if Sherlock's attached. He says he doesn't have a girlfriend. Not HIS AREA. Doesn't have a boyfriend, but he says he's FLATTERED that Watson asked. Watson says he wasn't asking, but it's fine. At first it was a lookout, but when they get back Home Sherlock says it wasn't and they were there to pass the time and prove a point. At the end, asks Watson if he wants to go to a Chinese restaurant WITH HIM. "The Blind Banker", Watson meets Sarah, likes her, and asks her out. At the flat, Sherlock asks if Watson wants to go out. Watson says he has a date. Sherlock says THAT'S WHAT HE WAS SUGGESTING. Upset when Watson and Sarah are together. "The Great Game", deduces Molly's boyfriend is gay. He's brilliant, but it's not easy pointing out a gay person. Du “What if they wear bright Farben and stuff?" Misconception. Could like bright Farben and be straight. The only bright clothing Sherlock noted Jim wore was his underwear. How Sherlock deduced instantly that Jim was gay, he himself is. When trying to deduce what Moriarty wants says he thinks he wants to be DISTRACTED." At the pool, Watson comes out and Sherlock is shocked, not only cos’ he thought Watson was his partner but cos' he had feelings for Watson. Near the end rips off Watson's jacke and asks if he's all right. The awkward moments between him and Molly. Sherlock only compliments her to get what he wants. Callous to her. “A Study In Pink”, starts to ask him if he’d have coffee with her. He doesn’t want to hear this, so interrupts her with the lipstick quote to confuse her. Ends up asking him if he’d like coffee. He says “Black, two sugars. I’ll be upstairs.” 2:He’s straight. No idea how to act around females, no experience with one. Acts strange around Molly. Gives her awkward compliments like the lipstick, her hair, and others. Upset when he sees her with Jim and she says they’re dating. Tells her the wrong way Jim is gay, doesn‘t mean to. Tells Watson to take Sarah to a circus, Sarah says she hasn’t been to one in years and she’d Liebe to. 3:Bi-sexual. Evidence is there, just need to combine. 4:Bi-curious. Doesn’t know which he likes best, so tries both. 5:Metro-sexual. Doesn’t want Molly to get hurt cos’ of his work, so acts gay. oder is afraid of sayin’ he likes her, so acts gay. 6:Asexual. Du know why.

I wouldn't say he was asexual because in hlv he has sex with janine even if he has no sexual oder romantic interest on her he still does i believe oder would like to believe he is bisexual as he is obviously interested in men and definitely Irene adler and there is far too much sexual tension in the whole Zeigen for him to be asexual
