Girlfriend Wishes She Could Orgasm Faster

My girlfriend is always lamenting that she wishes it didnt take her so long to orgasm. We usually try to hook up in the morning before work and she stops me when I start licking her or using my fingers because she thinks there isnt enough time. It kinda sucks. She doesnt get off during intercourse. Is there anything that can be done here? Why does it take so long, long enough where sometimes she thinks its not worth it? Im willing to put in the work, but sometimes there just isnt enough time.

Kinda cruel you know, the fact that guys can come really fast if they want but have to hold on to satisfy the woman, and the woman takes forever to be satisfied. I wish there was a special button to push to make her orgasm. Im pretty sure im hitting the g-spot with my finger but it doesnt seem to do anything for her. An old girlfriend used to orgasm from it and I barely stimulated her clit because I thought it was all about penetration. This girl just orgasms from clit stimulation.

Can a girl please give some tips on this topic so that guys know without a doubt where the g-spot is along with any other tips and tricks that will make our women hot so we dont feel guilty about them not getting off or thinking that they arent enjoying themselves when time is limited. Any advice would be appreciated. Please post anything that really works well to get her off quick? Any ideas on multiple orgasm? Im kind of a noob at this so even though she and I think im decent, perhaps were missing something.

Also, should I feel threatened if she suggests she dusts off her old vibrator that she hasnt used for a long time and have me use it on her?
