Open relationship

So ive been thinking it over lately and ive decided i would like my GF and I to have a open relationsip. Not just because i would like to bang other hot girls but also because I think it would be hot to see my GF give another guy a blowjob, maybe i could lick her asshole while she does it. Or even turn things up a notch.

I think life is too short to just have sex with one person. I believe in loving someone and being faithful to them mentally, but not physically.
