I'm 21 and he's 28... We both have demanding jobs as I am a nurse and he's a gas engineer but we have been in 5 dates in 10 days... I have a strange feeling of comfort with this Virguy :-)
Then work with that. He is old enough to know what he wants and mature enough to show his feelings. User be warned Virgos will be repelled by negative energy. If you get harsh in anyway he may shut down and do the most Virgo of Virgo things and disappear.
To avoid this be positive and above all if he critiques you for any reason UNDERSTAND and I mean understand that he is thinking of perfection as he see's it. And what I mean is that he is seeking the most useful efficient way of doing or saying something. If you disagree tell him nicely and discuss it with him. He will use a lot of logical arguements for the new behavour, they are not put downs, remember that, he just see's a smarter way of doing things.
He will change his behavours over time to match an efficient manner he sees. Do not worry this will be normal.
