<human>: I've been in a relationship with my girlfriend Kate for two years now, and we've been friends for about three. We lost our virginities to each other, and we good friendship. We're currently in a longish distance of about 3 hours but we try to see each other on the weekends.

I'm going to keep out a few unnecessary details below for safety reasons:

I've started to recently have a quickly developing career in music and have been approached by a lot of women. I know these are women that probably don't like me but just want to get with me because of fame, etc. I know I would never cheat on Kate, but I'm worried at some point, especially being that this is probably going to be my life looking on from now, I might want to discover what other women are like. 

I can't just break off the relationship for a few reasons. I love Kate, and I fear that if I break up with her I might have a month of fun then start missing her again. We've been through a lot together (at least what I consider a lot being a 17 year old) and I don't want all our memories to become meaningless.

Please help ASAP, I'll likely take this post down after a few days.
Thanks.
