<human>: Give me the gist of the text in a nutshell

I started dating this guy almost half a year ago, last week he introduced me to his parents - we went out for dinner with them and then the following weekend he cooked dinner for us all at his place. He told me in the beginning that he has commitment issues but during the 5 months we've been seeing each other he's been nothing short of wonderful. The dates have been awesome ( treasure hunt picnic, worlds first underground giant trampoline, zombie survival quest ) and he has been affectionate and intimate with me. I'm not a clingy type of girl, he's told me that he finds me fascinating and thinks that I'm a rare find but has expressed his desire to 'fuck other girls'. He told me that either I'm okay with this, or we'll go to being 'friends' because he values knowing me.    

I like this guy, it's only occurred to me since he said this 2 days ago that I haven't thought about or looked at any other guys since meeting him. I don't want to be taken for a ride and left heart broken in a few months but I could very well be okay with sex outside of the relationship as long as it was just sex and not intimacy. He wants an answer soon and I can't quite gather my thoughts or appropriate questions to ask at the moment because I feel so confused. Has anyone experienced an open relationship or polyamorous relationships? Insight appreciated.
<bot>: My guy wants to fuck other girls as well as me, is this possible within a trusting relationship or am I being taken for a ride?
