<human>: Can you give me a shortened version of the text?

So I have been dating my gf for about five years now and everything is pretty good in our relationship. Nothing that would make it bad or unhealthy really. But I personally have a problem that being I feel bored with our relationship intimately. For more depth, we started dating my last year of high school and is the only person I have had sex with. I do find my gf very beautiful and attractive, it's just that the urge and craving for sex or any foreplay even has disappeared. I don't know if this is my body trying to tell me something ro what, I am just confused. Why wouldn't I want to have sex if I find her attractive? Something I feel terrible about it is if I see someone attractive I know I'd definitely be in the mood to have sex with them, but I also understand that's how it is with any brand new relationship, you just want to have sex all the time. Which I understand is part of the relationship to have that fire dwindle, but completely gone? I just feel like we are an old couple that's been together 30 years or something.
<bot>: Been with gf 5 years, only girl I've had sex with, urge for intimacy is gone for me, have no clue why even though I am still attracted to her
