What's with the general notion of people looking down on you for not having no relationship even if you might had chances

I am 31 and in liberal crowd . I have several women friends as well as men's friend I am also a neurodivergent and a late bloomer that's why I only started dating at age around 28 When I tried to date the person I was interested in , rejected me for one or two reasons and the person who were interested in me , i did an explicit rejection that I am not feeling vibe . I was in high pressure academic environment and couldn't give much time to this All the feelings of discourse about relationships makes me feel bad maybe i should have gone ahead with the Relationship to have a relationship expierence for the sake Wouldn't it would be bad if I be in relationship just for the sake of beign in relationship and unfair to women Why i had to jump through hooks to tell an elaborate story why i never had been in relationship constantly thinking if they would look down on me
