Still horny?

My husband likes to masturbate so I try to do it too. Sometimes I can get off several times but it never like fully satisfies me. I'm still horny and I still want to have sex. I've used my imagination, porn, and toys. Husband says that I just don't know my body well enough and need to just experiment with what feels good. Like I said I can get off multiple times during but I still want to have sex. Is this normal? Any advice on how to enjoy it more?
