someone please give me advice ☺️

i’m 20 years old and my husband is 25. I am a horny person and so is my husband but i’m just super horny most of the time. My husband works everyday and i understand that he’s tired from work. We have sex about 3-4 times a week. So here’s the problem ... I sometimes get upset when he doesn’t wanna have sex and it starts an argument in bed between us. i do understand that he’s tired but i feel like we’re married and should be doing it a lot. He says that we DO have sex and we do but i always want more. we aren’t trying for babies yet but still .. shouldn’t we do it a lot ? our relationship is amazing besides that. He’s an amazing man and i’m so i love with him. Before we got married i never had sex with anyone, do you think it has something to do with my age ? because i’m so young and i’m just starting to experience sex with my husband? we have been married for almost a year in September.

ps i have no one to talk to about this except to share this on glow.
