dear masters!
I've just got a question that i'm stuck in explaining why and how. Please give me your ideas.

Me and my gf have just about having some foreplay, i licked on her.... and just my tongue got into it but after that we found out something like blood stance on the bed. I'm wondering whether has she lost her virginity. Just by doing that how can that thing happened.

Any response would be very greatful.

Thanks
