Is it normal am i still a virgin, if i had oral sex?

I am 18 now, and in relationship with a girl from College. We just hang out, but havent been to sex yet. When I was 15, I used to babysit children. One day I was babysitting a cute little 7 year old girl whoes parents had gone to a night club. After helping the girl with her homework, I put her to bed and went to watch TV. I was watching a sex scene (that which I was definitely not alowed to watch at my own house). All of a sudden I had a very bad *****. I thought of masturbating, but a lustful image if the girl came into my mind. I went to her room. She was sleeping with her teddy bear. I started kissing and brushing her preety little legs. This woke her up, and seeing what was happening she giggled. I could see that she was enjoying so I opened my zippers and took out my penis which was larger, stiffer and hotter than ever before. She held it with her wonderful hot little arms and it felt great. I told her to take it into her mouth and suck it, that which she did while I brushed the rest of her body. Soon her mouth had my hot ***, and I was satisfied. We both loved it and promised not to tell anyone. I kissed her on the cheek one last time before saying goodnight. I brought her picture and a pair of her shoes with me, and cant go to sleep without them. I never went near her house after that, and she and her family moved away few months after the incident. My girl friend offers me sex, but I refuse her because I want to remain virgin forever, and I cant wash out the memory of that girl whom I realise I love. If I am ever to lose my virginity, she will be the only one for me and I hope to meet her again someday. But the question is have I already lost it? If yes, I will still be happy as it was her!
