When I experimented, my senior researcher asked me "Don't you feel uncomfortable when I talk about erotic topics?"
I replied "Not at all. On the contrary, I'm often blamed for tweets which include erotic or indecent contents."
As is often the case with conversation among men, they like to talk about erotic topics.
In addition to it, my senior researcher's experience on having sexual intercourse is beyond our imagination, and I have interest in it.
Tomorrow, I'll carry an experiment with him in Osaka University. I'm looking forward to hearing about such topics.
