<human>: Condense the text into a few key points

I posted in relationship advice subreddit about whats going on if you want to read it: 

I want to know is anyone in a relationship where you never had the initial stage (spark, sexual elecricity between you) stage. I'm (f18)with my boyfriend (18) of 5 months and he is everything I could have hoped for in a boyfriend and more, but I grew up thinking that in a relationship you need that spark, that instant attraction, that electricity. I know it doesn't last and its not something to hold onto in the long run.

Its like our relationship is feeling like a real solid one you get years after the initial stage. Its romantic, sweet, and I feel completely at ease in it and feel so much potential for it to grow into something stronger.

The thing is I do not feel AMAZINGLY sexually/physically drawn to him. But I'd lie if i didn't; I find him really cute and he is really attractive. I kind of go blank when we do anything further than kissing. I don't know what it is.

I am willing to continue this relationship; but I sense that there will be some kind of trade off involved; fantastic friendship, great communication, romantically on same page etc and literally everything else a relationship needs to function healthily rather than a great amount of sexual attraction. I am okay with just having 'good' sex but don't want it to deteriorate and need to know if its worth working on or I am fighting a losing battle.

I feel like our relationship is endless with possibilities and we can grow together, but I need to know if this is something we can get by. If you have a successful relationship/marriage like this, please tell me your situation, give me advice, will it work if you're willing to accept these things?
<bot>: Great young relationship with a lot of potential, no spark but willing to look beyond that because we have better things that are generally hard to find in relationships. Would like to hear from anyone in the same relationship, or far along.
