<human>: Can you succinctly summarize the text in 1-3 sentences?

I know we are only in highschool and just seem like kids, but I would really appreciate it if you would forget about that.

I've been friends with this girl for around two years now. We've talked a lot over these two years and I've helped her through break ups and family problems and what not. Everything seemed fine until Sunday, 11/17/12. This was the day things changed.

Late Sunday night I was talking to her. Telling her what was going on during the past week because I was out of town for a funeral. This was the part when it got wieird. I'll give you all the conversation:

Me: Babies. My little cousin Leah had me play horsey all day yesterday. My clothe
s were filthy afterward

Her: You can play horsey with me ;)

Me: Um that escalated quickly

Her: But forreal. What would you say if I proposed a "one night stand" type of thing? 

Me: Sure why not? There's no harm

Her: No strings attached, just a friendly theft of virginity. 

This was where I had no idea what to do. And I still don't know what to do. We still talk perfectly fine. 

What I do know is that even though she says that there are no strings attached, there will be. No doubt. But how will this affect of relationship as best friends? I don't want it to be awkward afterwards. 

I also do know that I shouldn't just lose my virginity to just someone I care about a lot but someone I can love and be loved back.
<bot>: Best friend of 2 years asked for a one night stand. I don't know how to go about this in anyway.
