Laughable? No. Society puts pressure on people to stay virgins, and to be "successful" sexually at the same time. I think it's a bunch of bullshit. Very complicated topic, but that's a quick summary for you.
If it's a personal choice, I have *nothing* to say. I fully support individual choice, particularly in these terms.
If it's not by choice and you do in fact want to be sexually active and just haven't had the right opportunity yet... I might think you were shy and didn't want to be rude to people when trying to flirt, so maybe no one ever picked up on your cues?
I hope that's helpful somehow.
