Hmmm ?

my boyfriend only wants to have sex once a week , and I don't want to seem like a sex addict but . once a week is not enough for me . and when we do have sex it's only like 10 mins if that before he cums . so I don't really ever get to get off unless I masturbate .. I feel like he isn't attracted to me .. but at the same time if that's the case then why does he get off so quickly when we do ? what is some good ways to secretly seduce him to get him in the mood . cause when I try he says babe I don't want to have sex tonight !! so frustrating
