The mom of one of my close girlfriends (from back in childhood) was a virgin until age 29. But then she got married and is still married to my my friend's dad who is now 81. And they are very actively involved in raising their granddaughter. You don't know what might await soon. Better not to think of yourself as too old. Especially nowadays when it is customary to live with parents.

I have a friend whose daughter is 29, still lives with him and his wife, never dated, never had a boyfriend, and is not missing any of that. He would have preferred for her to venture out, but he cannot make her and he respects that she is happy single. In your case, you aren't happy, but I am just pointing out that there are people your age, in your shoes, who do not find this state of affairs shameful.
