Hi. My fiance and I have done the same thing as you before (just the tip), and I still consider myself a virgin. I haven't gotten that hairline of blood before, but it might have been because you weren't wet enough. In any event, I wouldn't freak out. You did things the way you did because you didn't want to lose your virginity, right? Well, you don't consider "the tip" losing your virginity, so leave it at that. If you bled a little bit, don't worry about it. Of course, if the bleeding lasts more than a couple of days or you get pain or if it increases, check in with your doctor.

Good luck hon!
