<human>: Let me start off with yes, I know we are very young but I honestly don't think this is the issue. We have both gone through not great parenting that led us to be taking care of our parents financially and grow up a little more than we probably should have as kids. Background: We were inseparable friends starting at 15 and eventually shifted into a relationship around 17 which will be relevant. 

My boyfriend Mark and I have almost too much in common. Common hobbies, interests, sex drives, "neediness", etc. which is not the issue. I don't think I would ever find anyone so similar to me in those regards. We are very laid back, financially motivated, and enjoy just doing nothing together a lot of the time. 

Here is where I am very confused... I absolutely believe that the grass is greener where you water it and he is an amazing person and I could absolutely be happy for the long haul (five years down the road maybe) but I think my issue is the fact that we were best friends for so long before we dated. I think we gradually grew to love each other as friends and people first but I am confused because I don't think there is a lot of passion if that's the right word? I don't know how to grow to be passionate from being platonic friends with boundaries so long. 

We both care so much about each other but lately I'm having issues with myself. I'm tired of still acting like best friends more than a couple, I want to be able to start up more chemistry and passion between us! How do I do this and how can he start doing this without feeling strange? We are so ingrained as best friends it overrides a lot of the "coupley" aspects of our relationship. Does anyone have any similar experiences? We are so young there is so much time to work on it I just don't know how...

Summarize the given text in a few sentences.
<bot>: best friends turned into relationship but sometimes it feels like we are more best friends than a couple. How can I change this? Any similar experiences?
