Should I keep dating him?

I have been dating this guy for about 4-5 days. I like him alot and we have alot of fun together. He's met my parents and my nana. Everyone likes him, but we got into arguement, or talked about him being about only one thing. Before we talked about it, He was all about just having some sexual going on, I wasn't really into it and let it go, I told him it's like every guy I get just want's one thing, and then he apologized and explained that he didn't want one thing and that he was in love with me and would rather never touch me again then to not have me at all. Should I believe him? I'm 15 and He's 16.
