Virginal lesbian girlfriend

I am 24, 100% lesbian, and not a virgin. My girlfriend just turned 20, is questioning, and is still a virgin. She attends college 10hrs away so communications have been hot, heavy, and VERY descriptive but with the obvious physical hinderance thus far. We have both communicated our desire to move onto the next step when she comes home for break from school but I want to be sure that giving me her V card is what she wants to do and is comfortable. I know that virgins sometimes talk a big game but then get cold feet when it comes time to swipe the V card, and her questioning sexuality adds that much more complication and pressure. I want to make sure this doesn't happen because while it may be her first time, it's my first time with a virgin, and I want to make sure it's right for her...
