One bit of advice: that travel career and being married are almost mutually exclusive. Most guys I know who are married who have any degree of travel in their jobs are harped on about it if it gets too thick.
That said - I think you're suffering from what a lot of people in our day and age, even earlier are. You were fed a bunch of manure through childhood about what life is, what it should be, what you should be able to expect, the idea that you'll get everything you want in life by being a good guy, doing the right thing, 'earning' it, etc.. There's something to that in the work world to an extent but the L&D world is way more complicated.
It sounds like more than anything you have a psychological weight around your shoulders about 'never having been'; I do hope that changes in your near future and I say it for this reason - its very difficult to let go of the need for sex when you still have a very over-embellished sense of what you're missing. When it does happen you'll likely have a moment of existential panic like "What??? This is all it is?????" and at that moment I think you'll likely realize just how profoundly different you are, that NT's wouldn't even bother with it if the barriers were as high to them as they were to many aspies, and while its heartbreaking in one sense as in - you lose your virginity and the movie doesn't end there, you feel just as if not even more hollow than you did before if its not someone you're in a relationship with, there's also the upside that you'll likely start completely resizing your whole reality and the scope of the motivations people have around you, what's ultimately worth what, etc. etc.
