low libido or just overthinking it???

ive been wanting to go to the gyno for a very long time to talk about this but its very embarrassing for someone as young as me. i dont have a sex drive, at all. all my friends ever talk about is sex and i dont even think about it at all. when i do go to have sex its embarrassing bc im never wet, i dont self lubricate and it makes me not to have sex, idk if its the foreplay bc i WANT to have sex my body just isnt connecting with what my brain wants. idk if this is low libido or if something is wrong with me and is causing dryness or i just need to relax but, i cant have sex. im too afraid ill be embarrassed but i want to have sex idk whats wrong with me somebody help please.
