How can be good enough to be datable as a man?

I (28M) am new to dating, I have never dated in the past because I was very focused on my education and career. I just finished my masters in computer science and currently working full time in my career. The only issue is that a lot of women have said I am extremely ugly looking and that being a virgin at my age is a major red flag.

I understand I have made so many major mistakes but I wanna fix this and just become a better person for women for when i do go on dates. Dating honestly has ruined my life Dating has become extremely difficult for me and its ruining my life, what do I do?
