The pros of virginity are linked to circumstances which could be considered more "moral" than the entailment of accidental speed bumps. When I say moral I simply mean liberated from guilt.
For example, once a you're pregnant so is the whole family who have to sacrifice their money, time and effort to support you. If you come from a struggling household, your child will be born into an inadequate upbringing. If you consider having an abortion, there are religious codes you have to reason with, which is why abstinence makes sense as a religious value that was recommended in the first place. If the mother decides to have an abortion, she may feel guilty/traumatised and wallow in an unproductive lifestyle for a while. This whole interdependent burden could've been saved with a little patience and maturity.
Unless the suppressed symptoms of being a virgin for "too long" if not gratified sooner (pfft, for most kids these days it's <16) would've compelled someone to act dangerously out of sexual frustration, it's not more virtuous than virginity.
Of course non-virgins can be better people than virgins ultimately, but I'm talking about the consequences of taking the risk at such an early age, which virginity prevents and results in a clearer conscience, "Are my actions in the best in interest of those they effect?" It's not "immoral" to lack caution because people don't expect kids to have fully developed judgement and foresight yet, but that's the problem. If you lost your virginity at a young age and you were ready, have no regrets, to me that's validated, but I know of quite a few people who rushed into it, believing they were ready and came out of it an emotional wreck. With age, couples maximise trust and stability both in the relationship and individually before having sex.
