This is true. Once you graduate high school it's unreasonable to condemn a girl for not having had sex with one or two guys. As always, it's "quality" vs. "quantity". A woman who has had sex with two guys a hundred times each is far more valuable than a girl who has had sex with a hundred guys twice each, despite both having the same mileage.
The reality is that virgin men after high school were sexually abused (not just physically, but emotionally as well), on the autism spectrum and have elevated women to a level far higher than what they should be at, are social failures who can't communicate with anyone regardless of gender, or are blatant misogynists. In other words, in a world where women are so sexually liberated that men can complain women are having too much sex, it falls on the man for being unable to have intercourse.
Granted, men DO age like fine wine, but that particular vintage requires something to show for it. Just because a man gets older, if he has no property, money, or achievements, he's a green-label swill. Waiting for a woman to fall into your life just doesn't happen; you need to be active, not just physically, but also in your education and career. Women, meanwhile, age like milk; the older they get, the less valuable they become. By the time a man is about 24, it will already start being socially unacceptable for them to date an 18 year-old in the US. Time is of the essence!
Anyone is able to have sex, and if you have a dysfunction to the point where you are in a state of unrest towards the topic, there are therapists able and willing to talk to you about it. Do not let idealization, terror, or anger get in the way of experiencing the full range of human emotion.
