Why do people find it so difficult to understand that being a virgin can be a problem if you don't want to be one?

It's natural to feel bad when you see how time passes and others have sexual and romantic experiences while you have none of that. Although I don't feel insecure or value my life less for being a virgin, I'm not happy with my situation either, since sex and relationships are important to me. However, many people act as if we should be happy with the possibility that we could die virgins since sex and relationships are supposedly not that important, minimizing our experiences and saying that "we're not missing out on anything."

I know that sex won't give me superpowers, but I'm not stupid and I also know that it's not "nothing"; that's just a false way of wanting to make me feel better. People who say that probably wouldn't be satisfied if they had never experienced sex or relationships, since sex and relationships bring you things that no amount of hobbies or friends or work successes can, since it's about much more than physical pleasure: it involves intimacy, emotional connection and feeling desired, even if it doesn't involve intimacy it's still fun and enjoyable otherwise people wouldn't do it.

When I express my feelings about what I'm missing, instead of comfort, I often receive comments that seem to invalidate my desire to have those experiences. It's as if by mentioning what I want, I had to justify myself for it, when we all know, or at least I thought we knew that relationships are an essential part of the human experience.
