I don't think you're shallow, @

It is PERFECTLY NORMAL to wish for sexual satisfaction. I guess it depends on how much this is weighing on your relationship. Do you feel like this is something that can be worked on? Something that can be discussed with? Perhaps you can even try your luck with a Couple Counselling as I believe they can offer Advice and Support for this kind of things as well. Give it a thought perhaps! I feel like it's REALLY IMPORTANT to discuss things with her. If you eventually decide that perhaps it's best to let her go, don't feel guilty about it. You've made the best choice for BOTH of you in that case. Wishing you the BEST of luck in your Decision, whathever it will be!

Sending many safe, warm hugs to BOTH you and your Girlfriend, @
