This is like being afraid no one will ask you to prom (sorry, didn’t mean to give you another thing to feel anxious about, but “it even happened to me”). So what happens is no one asks you, the formal happens (with or without you) and you survive.
In your situation, Life itself will happen whether you remain a virgin or not. And you will survive. And no one will know (or think or care) that you are an Eternal Virgin.
What will probably happen is you’ll eventually and suddenly find a nice person and have three kids. You know, the typical Fate of All Women.
