Be smart but also caring, show the Virgo man you care...
Far from prudish, the Virgo guy is sexy and smart (hello Tom Hardy, Sean Connery, Ryan Phillippe, Keanu Reeves, Richard Gere!), big-hearted, charming - what's not to like?
Well, perhaps he's too smart for his own good, the way he overthinks everything to the point of near-immobility. He can be insecure, but a little love pumps his ego. And it will take work to get him to open up.
Show him you love him and his (real or imagined) flaws. Prove how much you appreciate him with words as well as tokens. Even the smallest loving gesture means the world!
