Never been on a date in my life, Is something seriously wrong with me?

I am a 19M and usually at this age, people around me at my age date and “have fun” but why I am so lonely been single my entire life, I also have decent height 6’2 and good facial features, is it something that I am missing that women dont like? There are some girls I know are interested in me, but they are not really my type, and the girls I do like reject me entirely without me knowing why, I asked out 2 girls, 1 said “No, cuz she was older” 2nd said “No” without any explanationg and left the 2nd one is in different class as me, but still keeps looking at me after rejecting me,

LIKE WHAT HAVE I DONE WRONG, I am sick of being so lonely and single, that’s why I devoted myself entirely on building a business, so I distract myself from this problem, But I do wanna figure it out

I do appreciate any advice I can get, I don’t even care to get laid, just securing a date is win 🙁
