As for what solution might work for us in this backward, evil culture, well, it's left to us.
I've in the past been able to discern when desire for even a single person would be disrespectful or undignified, and not in accord with the spirit of the law, which commands love. That to me is much better than a false understanding of morality which seeks only to inwardly castrate.
It doesn't solve all problems, though, obviously, if you encounter a single someone who wants to do things to or with you. If you're not willing to get married then maybe you just need to apply some practical wisdom and avoid trouble. But I would not try to alter your understanding of morality. Christians are not taught to have one understanding for a wednesday, and a different one for a thursday, or one view of morality for singleness and another for married life. That's simply not very intelligent, and it leads to more, and deeper immorality when you consider the remainder of Romans 1 concerning maliciousness and evil intent.
