I have been hooking up with this girl but we only really get it on when both of us are coming from the bar with a good few drinks in us. She has invited me to her place twice, both times we are lying in bed with our clothes on. She has told me she's been holding back her feelings for me because I will be graduating in a month. Because of this, she holds back when kissing me. I know that we are both trying to get it on ,but she's making it difficult when I can't even start it off due to lack of effort on her side. Any advice?

TL;DR 1 month of college left for me, freshman holds back on kissing but wants to fuck. How do I get her to fuck if she holds back on kissing?
