should it count??

So yesterday I called my guy friend over so I wouldn't have to be alone in my aunts house. I water her plants when she goes out of town. And when we finished I was all sweaty, so I took off my shirt. I was wearin a bikini. Well one thing led to another and we were naked and in bed. I had never had sex before but we were fooling around and he got it halfway in. But I wasn't at all ready and we didn't do much after because I told him to stop. Does that mean I lost my virginity?? I know this sounds ignorant. I just don't know if that should count.
