Rococo

I'm heading over to the 5 year mark of being with the same girl. I've noticed more and more that other girls are looking good. I mean REALLY GOOD. So what do I do? I'll tell you right now that I know I will never find a more understanding perfect girl. She's got it all, but I still can't stop looking at other girls. It's starting to drive me nuts especially now that summer's here and oh yeah, my balcony overlooks the beach!!!

Would I be a horrible person if I screwed around for a while, just to get this shit out of my system? or will i start some sort of viscious circle? I've already discussed this problem with my girlfriend and she says she understands but to just not tell her if I do anything and to be safe. But I know she'd be devastated if I told her one day i fucked another girl. And (yes I know I'm a hypocrite) I would not dig it if I found out she fucked another guy.

So what the hell do I do????
