Because you didn't make a move.. open google start search article how to woo girls. Practice it, by having conversation with girl. If you lucky you'll get laid at the end of the day. Other way ( not recommended ) try prostitute.. don't forget rubber.
This was mainly for lols. Somewhat fun to read the advice given so i can actually get female opinions of situations when i start chasing skirts. Not even desperate yet. Gimme 10 more years for that.
The thing is that you will likely fail a lot. Just like with everything else. If you ask out 20 people chances are a few will accept and you get practice either way. Not everybody is lucky to get a perfect match next to them. Just ask them out for a coffee, lunch or something simple. Show interest and ask to meet up again. If they keep meeting up you have succeeded in most cases (unless friend zoned, which is still success but of a different kind).
dude, in 10 years you'll be a wizard, do you really plan on giving up on that after you've achieved it?
