sex issues (too big)

Tonight, I finally had sex with this girl i've been dating. We went to dinner and started to watched a movie at my place when things got heated. I had known that my dick was the biggest she had ever had, but i was suprised when i realized that my penis couldn't fit into her vagina. I got her very wet but just wouldn't work with me all the way hard. It sucks because I really care about her.
