<human>: Summarize the given text in a few sentences.

So as the title kind of says. 

I think my GF may be interested in seeing me with her best friend. We spent alot of time with her best friend who goes to a different university over both of our universities winter breaks.

Because there was always just the 3 of us, the two of them started referring to me as both of their boyfriends. As Valentines Day approaches and my 2 year anniversary my GF told me to buy her best friend a set of lingerie as a "joke" for Valentines Day before I knew what I was getting her.

I know this doesn't necessarily mean she wants to see me with her best friend but it is rather weird she wants me to buy her friend a garter, a g string and thigh high fishnets, and ask her for a photo when it gets there.

Does anybody have any idea what may be going on in her mind. I'm sorry this doesn't have much context. The only context I can give is me and my GF have been having sexual issues due to vaginal issues with herself.
