GF wont give blowjob

Well here is the rub: it's not that it's bad that she hasn't or won't especially if she's never given one before. In my experience, first-timer bjs are the worst. There is a lot of teeth involved and a lot of instructing and it's awkward and it totally ruins the mood. So if she hasn't done that before, then her not doing it is really saving you a headache.
