I believe I first read this book around 2006-2009 while I was in middle school. I think it is part of two or three book series. I remember one of the covers was green with maybe a hurricane on it. If I remember correctly the first book starts with the main character and his girlfriend in his care and the girlfriend tells him to zip up his pants because it was not happening. The main character slowly learns he will be a king of some sorts in the future and his future wife comes to the past to train him. The book does have some sexual references to it so that might help. I remember the pair get stuck in a jungle at some point. Also at the end of the series *****(SPOILERS)***** after a battle a prophet of some sorts sees the future of the characters and tells the main characters ex that she will have a normal life with a husband and kids. I also remember the main character will at some point get a blue sword that may be made out of fire or even ice. The main character will also meet his parents who are warriors and fights alongside them at the end of the series.

Andres, what's the setting - e..g, medieval fantasy world with magic?

[Andres]

I would say the setting at the beginning has them in the modern world but then they might be transported to a different dimension or even the future. There is magic involved later.

Also it may be part of a three book series. The parents of the main character also fight together if I remember correctly. The whole family seem to be proficient as warriors or in swordplay.
