If you are looking for an abundance of devotion, he has it to give.So, in conclusion, if you are interested in a shy man, start by questioning that feeling. You will probably get frustrated at his lack of response to your initiatives.
Aside from their innate male tendency to overlook anything that isn't spelled out in black and white, shy men will by default doubt any sign of your affection.
His masculine instincts will kick in, and in some cases you can end up with a man that acts towards you the same way that a confident man would have acted from the outset.
So, if you do choose to initiate, do so only during the early stages of dating, that is, until he builds his confidence and comfort around you.
If they have even the slightest doubt about your intentions they will hold back.
So whatever you would normally do to indicate your interest to a confident man, double or triple it for a shy man (in proportion to his shyness): While I don't suggest that you overtly ask out a shy guy on an "official" date (this would too flagrantly undermine what he knows to be his role as described above), I do suggest that you suggest and then ask him to hang out under casual pretenses.
The reason for this is that shy men are more concerned with avoiding the social catastrophe of asking you out and failing than they are of getting you.
