is this too much?

so i have always been a very sexually aware and sexually driven person; since i was litterally a child tbh. the thing is since i have such a high sexual drive i just think about sex a lot. i mean it takes up 80% of my day where i just think about it. i watch a lot of porn and i masturbate every day at least 2 times (when i have a free day i just spend it by watching porn and masturbating). i often think about it in public or makeup scenarios of me having sex with random people and it's coming ti rhis point where i basically just think and keep wanting to do it every day multiple times a day and when i do masturbate or have sex it's never enough for me and i keeo craving for more. now my question is, is this normal? am i the onky one like this? is it maybe because i am just 18? i would appreciate some help thank you 💛
