I'm a 28 year old kissless virgin who has never experienced love/romance. Lust yes, actual love/romance no. Wasted a few chances, and yeah it was painful at the time. It gets less painful with age, though that's mostly because I'm not actively seeking it out - if I were I'd be looking for a wife and a mother of my children, not a pump and dump headache. Relationships are a big commitment in terms of time and money, and I'm not keen on wasting either.
I know two guys who've had relationships and have been broken up after they ended. One was an old coworker who ended up hanging himself - only child, parents devastated. The other guy is a friend I've known for over a decade who's now addicted to chasing puss on Tinder. He's had a fair amount of success, but he's not happy and drinks a lot when we hang out.
Neither scenario is good, but I'd rather take my chances with the former. The kissless virgin part has almost no meaning any more. I could Google an 8/10 escort and have her over here in 30 minutes if I wanted to. KHV means you're playing the long game - put in the work on yourself now to reap rewards later. Get a good paying job, work hard, lift weights, and read books. If you're in your 20s, all the better - grind like hell in your 20s, easily the most important decade by far.
Also, despair is a sin, it means you're turning your back on God and stroking your ego feeling sorry for yourself instead of putting your faith in Him and putting in the work. Go to church.
