Just deal with it. Every man gets urges and has a wandering eye, why do you think two of the Ten Commandments have to do with sexual prudency (no adultery but also, separately, not envying your neighbor's wife)?
Stop watching porn too, it's making you identify women as purely sex objects and it's building a virtual harem in your head
>my gf likes women too, so to try making the things legally, i said her that if she wants to have sex with a girl it's ok for me and i would like to watch at least, but she refused and said that she would hate to see me looking at other girl naked, and it would be even worse if other girl was looking at me naked
There's no point in dating a bisexual woman if she's not gonna be ok with you getting in on the action, you're just gonna deal with the mental illness of having a rainbow alphabet person in your life.
Judging from her reaction she was either a college bisexual and still identifies with that to be "unique," or she'll eventually go full dike and leave you for some chick who's the goddess of eating box.

because that's normal
>what should i do?
1. Not cheat
2. Find another girl who's willing to let you cheat
The real question. Do you think you can resist cheating?

NEWSFLASH FROM AN OLDFART:

You will ALWAYS be tenpted. Maturity comes with deciding not to give in.
