Are you still a virgin? It's not really black and white. One one hand there was partial penetration but on the other you didn't have sex either. Some people say you should go by whether or not your hymen is still intact, but that's not a good indicator either, cause you can break that masturbating or even riding a bike. Maybe you should ask yourself this..
Did you enjoy the experience? You got aroused to the point of asking for partial penetration, you didn't bleed or hurt, and you felt happy after it happened. So maybe it wasn't romantic or with someone you loved but it does sound like you had fun. And if you enjoyed the experience I don't think you have anything to feel guilty or ashamed about.
Therefore the next time someone asks about your virginity, you should be able to hold your head high and announce that you're not a virgin. But if it either bothers you too much or you don't think partial penetration qualifies, you can just as easily say you're still a virgin. It's your call. Go with what feels the most comfortable.

I am a bit hung up over this, but compared to before I am much better.
