May I take a stab in the dark and say that the major parental influence in your life so far has been your mother?
Your sense of romanticism appears not to be linked to 'who you are'...in other words, it appears you a likely to bend over backwards for a girl, and give them everything that 'they want'...this won't work. Women want you to be nice because of who you are, not because you want to please them or make them happy...and they can tell the difference. The lesson in that is - work on having a life, standing up for yourself, going after what you want, being respectfully persistent, having focus, achieving etc (these are all qualities that women find attractive, though you don't have to possess them all)...and having a sense of humour.
You can be geeky and develop all of this - though it usually takes a fair degree of courage (and if not courage, then determination and persistence)
I would also like to point out that your restrictions on what is attractive is...way
to restrictive. In all of high school, you can barely find a girl who's attractive to you? Seriously?...and you think you're going to find one by...what...magic?...out there in the 'online world'? This isn't said to be harsh. If you wish to limit your partner preference to one in say, 2000...that's up to you. Just one further question on that - how many women do you expect to meet, in the next 10 years?
Other than that...you could practice by jumping in the deep end...it's not a bad way to learn, if you can handle the fact that you will likely suck the first several time or more.
And one last thing...the way you want to be with that 'someone special'...you should practice with every woman. I don't mean the intimate stuff, but being : charming, self-assured, funny, assertive, go-getting, energetic, listener etc. In being that way with all women...that special woman will still be able to tell when you mean it for her, and her alone...and you'll be more genuine about it....
....because it will become part of who you are, with practice...much like musician seems to naturally play his/her chosen instrument, so much so that they can convery their emotions / excitement / power etc through their music (ie it becomes a part of them)...but to get there, they had to practice and practice.
