So, we've known each other for 2 years, he is my closest friend in college but we've been a roommate since a month. I little bit attracted to him. One day, I accidentally opened his twitter, the other twitter account (which he used to watch porn). It really surprised me because he retweeted some gay sex porn videos besides straight porn videos. He also followed some famous gay of twitter user. So, what should I do to make him tell the truth? Or should I give him a sign?
