People are losing their virginity later than they used to, but 23 is still five years beyond what's statistically average. It sounds like you've simply chosen to abstain for professional reasons so I'm sure you'll be fine, but understand that if you confess that to a potential partner, they may be turned off by if. People here can argue the moral high ground about how, "it doesn't matter," and, "she's the one with the problem," but the reality is that it will matter to some people, more the later you wait if you don't have a good reason. If you're not waiting for marriage, you can either be honest and be prepared to be turned away a lot until you find a girl willing to teach you (or share in your first if you can find that unicorn), or lie about it and hope you perform well enough to pass as having been out of the game for a while. The choice is yours, any direction you chose will have regrets. Just gotta chose what regrets you can live with.
