You can't unless the admins specifically remove them... you will have to contact an admin @RedRain and tell her why you want the question to be removed... but I think they will only remove it when it is against the GaG guidelines1

Hi! Actually you can't delete your questions but you can disavow them after 24 hs of being posted. That means the question will remain on the site as anonimous, but you'll no longer own it.
This is how you do it: http://www.girlsaskguys.com/faq/features#157
