Is this normal?

Right so I’m 17 and i’ve been masturbating for years and believe me i do get horney, i watch porn and it does really turn me on, but when i look at guys and stuff, if they are wearing tight pants and you can see there dicks and stuff, i just don’t feel anything. If there are guys who i think are attractive with their shirts off and stuff, i just don’t feel horney. Is this normal? Just my friends and things tell me they can get turned on by a guy instantly and just wanna fuck em right away ya know, but i’ve never had that feeling :/ its made me question my sexuality thinking maybe im attracted to women, but then i’ve never felt the same way with them either. then i think well maybe i’m A-sexual, but at some point in the future (hopefully near 😂) i want to have sex! I’m just so confused and really wish i could speak to Otis’ mum from Sex Education rn but this is the next best thing! Someone please give me advice!
