What is your opinion on adult virgins?

Let's get extremely direct, but detailed again. You are concerned about not yet sticking your condom covered penis into a living orifice. This has zero effect on how I assess a person's value as a friend, human being and member of a social order, or worthiness in any interaction of life. You should know many unmarried people exaggerate their sexual escapades. You should also know that for some paper with dead people printed on them you can accomplish this self-inspired goal. Today, we have protests and new recognition about skin color inequities, a global pandemic that required a massive economic response, a new ruling yesterday for the LGBTQ community extending rights in the USA, and finally some are waking up to recognize the massive skew of wealth is a major root cause of more than they thought. This is among other things such as where your future is going personally.

Now, you are a fine young man with a life ahead of you overly concerned about little things, and I would focus on where the next 10 years are to be going in your life. Because at 20 years THAT SHOULD BE what is on your mind. 18 to 25 is the early adulthood where you should aim for both setting up your future and finding your passions. 

About your detail, height normal, great age to be, personality within social norms, healthy enough body (that can always be improved especially at your age, probably good moral standing, not realizing many people look at everyone with disgust and look down on everyone.

I got somewhat old after more than half a century on Earth and will give you some of life's wisdoms in short form that evade people.

1) You can only control yourself, influence other people, and many events are totally out of your control. Focus on yourself, improve your interactions, and blow off failures and setbacks only trying to learn and not dwell on things that happen that aren't your fault.

2) Time is extremely valuable. Your personal integrity is extremely valuable. Those you love have high value. Basic needs of food and shelter and health have high value. Everything else is less important. Use your time better and keep true to yourself, and show and express the love.

3) The past is gone as it happens. The present is all around you. The future is yet to be and you can shape your own. Keep your timeline in the right perspective.

4) The ultimate goal is to be happy. Decide what that means to you and make it your new prime goal.

5) People can be cruel. People can be nasty. People can be harsh. Most are amazingly ignorant and selfish. Those people who are not good people should be disregarded as much as possible. You can't fix them. Find those you respect and cherish them and become one of them.

Think about it. In this page I wrote, do you disagree after reading it carefully?

And will note, and be too bold here, if you were bisexual, the ease of getting your quest accomplished is measured in hours.

Either less then human or more ! Some greats are included & some incapable!

Unless you are wearing a sign on your chest that says "Virgin," no one is looking at you with disgust because you are still a virgin. It sounds like you have issues with self-loathing and lack of self-confidence. Women are attracted to confident men regardless of their looks. Get some therapy to work on your issues.

People get too damn hung up on virginity and act like it's such a weird thing. It's not. It just means you haven't had sex yet. Your lack of sex is NOT what is isolating you from people or causing women to look at you in disgust. It's your attitude and hangups about sex.

For crying out loud, just go find a woman and have sex with her. Problem solved. Virginity is a social construct anyway.

Why not take a look at the article below which discusses the subject of virginity in a positive light. :)

Assuming that happens, it's not because you're a virgin.  While you are on the older side, you aren't that old, it's not like you are say 50.
