Kevin has passed on dating, parties, drinking, mass-socializing, throughout school/college to focus on himself.

Why? You don't like to have fun? This is a problem. Girls just want to have fun.

Perhaps in his spare time he plays golf, rides sports bikes and tinkers with cars,

These are fairly interesting and decent hobbies.

Kevin lives in the United States and has his mind set on "finding-the-one" who has also preserved their virginity.

But why?

Will Kevin find his way or is he drunk on the Kool-Aid? Will he find himself still a virgin at 30 with his only options being the left-over high-school promiscuous cheerleader and single moms who want stability?

A 30 year old virgin? That would be a huge red flag. You wouldn't even want that woman. Or are you asking if you can find a 18 year old virgin at 30? I don't know it all just sounds weird. Why a virgin?

It is becoming increasingly apparent to me that men without interesting personalities (at least to women) will be unable to compensate for this short-coming with money/resources in developed countries like the United States.

Well yeah, maybe be a more interesting person?
