How to get in the mood easier?

So for me I used to watch porn when I was younger because obviously I didnt have sex lol but As I got older I’d get horny off and on I could watch an awesome porn video and be super horny (not every time) but if my hubbys horny and is wanting to do it he’ll ask me if I’m horny and I say yes..but I’m not...(of course I’d really wish I was..) but for some reason I just don’t get aroused easily but I love sex..in the past I have felt my pussy throb form being so horny (we started dating when I was 14 and he was 16) yes we had sex too..but I’ve gotten so wet but I just really never feel horny idk what being horny is like I guess..it makes me sad..is something wrong wm?
