I just came across this post on a blog which I think has many useful points of advice by Saint Nikodemos of the Holy Mountain.
We have reached in our discussion the fifth sense, which is the sense of touch. Even though the activity of this sense is generally considered to be concentrated in the hands, it actually encompasses the entire surface of the body so that every feeling and every part and every organ of the body both external and internal becomes an instrument of this sense of touch. Guard yourself then with great attention from such tender touches that arouse strong feelings, feelings that are mostly in the body and most vulnerable to sin. St. Gregory of Nyssa, in interpreting a passage in the Song of Songs, commented that the sense of touch is the subservient sense, the one most likely created by nature for the blind. It is most difficult for one to be free from the power of this sense, once it has been activated. This is why one must be careful to guard it with all his power.
