Is my girlfriend's best friend too touchy feely?

So my girlfriend is rather touchy feely... she doesn't invade people's personal space if they don't want her affection, but generally, she loves giving hugs and pecks on the cheeks to her closest friends, and just people in general that she feels comfortable with.

And my girlfriend's best female friends... they're rather similar to her. They gladly return her physical affection, and love being close together often.

But this one other day, me and my girlfriend were having a sleep over, and her best female friend of all was with her.

And her best female friend is great, really. She's very nice, and a great friend to my girlfriend, and even I'm rather close to her.

Then it got late, and of course we were off to sleep... my girlfriend only had one bed in her house, but it was one very big bed, enough for all 3.

And my girlfriend went to take a shower... just me and her bff were in the bed. I took the opposite side of the bed from her, but then she just came to me, hugged me from the back, and said, "It's this cold, and you want to sleep away from me? Come on, we're all best friends here! All because it takes place in a bed doesn't make it sexual. Plus, I have a boyfriend, as you already know."

Then I just turned and hugged her back, and attempted to sleep... I was kind of nervous, because she's almost as attractive as my own girlfriend. She's not my type, as her skin is too pale, and she has blonde hair... but she still is attractive.

Then my girlfriend came out of the shower after 25 minutes, and she just laughed and said, "Ah, you've already started to snuggle without me?" Then she just got in the middle and said, "This is great! Snuggling on a cold winter night, with both my boyfriend and bff beside me!" Then I was really relieved, as I as then hugging my own girlfriend, and it didn't matter whether I felt a bit of lust towards her or not.

Now back to the actual question... it was totally fine, as my girlfriend was fine with it, and her bff didn't do anything bad... but I still feel she's too touchy feely.
