Yes, I am not trying to make contact with the girls in my class;
I know girls in other places, and I have dated a few of them in the past, so I focus more on those girls.
I have noticed that the girls in my class seem to use various tricks to "tempt" him;
for example, one time when he sat down somewhere with some girls one of the girls stood up in front of him and asked him if she looked good in some leggings that I think she had bought, and turned around for him while he had a look, and on another occasion right before a lecture there was another girl who sat next to him and had a conversation with him, and she was apparently showing him some birth marks that were on her breasts (she had a low-cut top that time) and said something about them while smiling a lot about it.
Imight be imagining things, but I got the impression that they were doing these things specifically to make him feel comfortable with looking at their bodies - who knows.
