Need help with my gf(f33) and our love life.

r/

Me (34m) and my gf (f33) are in a happy relationship for 5 years now. At first our love life was amazing, doing the stuff you only see in movies. But since 1,5 year that magic is gone. And every time i mention that we get in an argument. I really miss those times where we had a deep connection, and i want that back. She wants the same, and her mind says also that see wants it. But her body says no everytime we go a bit further then kissing. I am willing to do everything to get the magic back like we had it. Who can give me some good advice or is willing to discuss it (via Telegram is also possible). Let me know!

TL;DR; : help us to get our love life back like in the old days.
