The problem with citing biological imperative is that you can use that as an excuse for anything that isn't out of social norms. It we aren't "hard wired" to let women have jobs, we aren't "hard wired" to accept homosexuality. These are absolute false equivalents, but that type of argument doesn't necessarily hold a lot of weight since there isn't a firm scientific interpretation saying "your brain says you MUST, in all circumstances, have sex or you're broken".
There is absolutely the potential for a healthy, well-adjusted person with a low sex drive (either due to biology or private past experiences) that would still fit most people's definition of "normal". Handsome and successful
Tim Gunn isn't a bad choice to use as an example.
Of course, and I know this is probably your point, someone who isn't forming physical and emotional bonds with another person, yet wants to and is suffering because for whatever reason they cannot, and as a defense mechanism decides to "give up", seems to be caught in a a psychologically unhealthy mindset. Unfortunately some minor internet bullying or well-intended arguments in this thread probably don't accomplish much, and professional help might be the better route to uncover and deal with what some of the underlying issues would be (if they stem from more than just the poor choice to buy a fedora).
Also jeez, how do you meet people in general? Some people meet significant others through college, bars, okcupid dates, but then some people are stuck in very small towns where they feel like an outsider, or they're at a phase in their life where they're working in an office with four other people and their spin class is mostly people 20 years old than them. Sex is the easy part, finding an appropriate person to share it with is hard.
