am I normal??

So growing up my parents literally never talked about sex with me. Like it was non existent and I basically learned everything from porn and what my friends told me and urban dictionary. So last night I was trying to get myself off but it was taking forever. Like 10+ min. I don't know if this is normal or not because the only thing I've seen is if a guy touches a girl she pretty much starts orgasming on the spot. I don't know if I'm doing something wrong. It felt good and then kind of went away so I had to stop and try again. I just want to know if I'm normal or not because it's not the sort of thing you ask your parents or your very sheltered best friend.
