<human>: For starters, I am absolutely in love with this girl. I don't think I can love anybody as much as I love her. She's still very pretty to look at, she's absolutely stunning and my friends think so too. It's just I don't really feel like having sex sometimes or doing anything with her. I just like lying down are relaxing with her. We've been dating for almost 2 years. I see other hot girls and fantasize about them but for some reason I just can't seem to get that arroused by my gf anymore. She's a great person too. I need help because I want to fix this, I don't want to leave her but I don't know what to do.

Can you give me a shortened version of the text?
<bot>: I(19M) don't think I'm sexually attracted to my gf(19) of 2 years anymore but I want to change it.
