Herbert did not have much experience with the girls, because he simply did not know how to attract the women who were imponated. It was in part his quiet and shy nature, and the girls on the shy boys might not be much of a lie, because if they did, Herbert would have had twenty of them on each finger.
Probably the ladies didn't even notice him, they probably didn't even know that there was, because Herbert usually tried to pretend that he didn't exist at all, as it was easier than to try to get to know someone or flirt with someone, so that just a moment later he found out that no one is not interested. It was easier to pretend that girls were not interested in it, and that it was too much to be so crippled as interpersonal relationships and their deepening was simply too elevated. He was sure no one would hurt him like that.
