First, do you like this guy? Is he nice? Does he treat you well? If you answer "yes" to these questions, then only you can decide if you want to continue with the relationship.
It is important to remember that no one person can fulfill all of your needs. If he is lacking in one certain quality, he might more than make up for it in other areas. Is it possible that you really don't know what you want at this point?
Just try not to hurt him. If you do like him, then give this some time. If you really don't feel that connection, then it would be best to cool things before you get too involved. If you need to do this, try to approach the subject with as much compassion as possible.
Take care,
