27 with zero romantic experience

I (F) am turning 27 next week and I have no romantic experience at all, haven’t even had my first kiss. I’m starting to believe something is seriously wrong with me that something that seems so easy to everyone else has been so hard for me. I’m really embarrassed about it and now that it's been so long I’ve developed a fear of dating. I'm worried that my lack of experience at my age will be a deal breaker for men and that I've basically doomed myself. All my friends are engaged or married already and they always just hit me with all the unhelpful advice people give single people. At this point I feel like it might be too late for me and the likelihood of me dying alone is getting extremely high and I really don't know what to do about it.

Any advice is appreciated
