you were just massaging her breasts last night and she didnt mind, girls know exactly what they're doing. Not to mention that you came to Reddit to discuss it because youre still thinking about it and clearly liked it. There's clearly something there mate.......... My statement stands

You are 17 years of age, i dont care if youre gay, bi or figuring it out... 9.5 times out of 10 men and women CANT be "best friends". This debate is very old and it becomes clearer with age.... Of course exceptions can be made but the general understanding is that unless 1 of them is uglier than their counterpart or gay, or unless there was already a failed attempt at changing the relationship, its not really a best friend relationship but a dormant platonic endeavor, in which 1 party is waiting for an opportunity... Dont lie to yourself, if you like this girl you must go and tell her what you're feeling like a man.

I'd start with this: Dear miss ex-best friend I cannot stop thinking about last night and i need help processing it, in person of course.

Good luck and get ready for massage part deux
