Catholic Boys: Altar Boy Marcus, Vol 1, Chapter 4: Altar Boy Training. I guess I knew I didn’t like girls but I tried to be a good Catholic boy. I never looked at porn on the internet and tried not to think about sex at all. Not really wanting to think about girls just made it easier. When I saw my roommate doing it with his friend, though, it opened up doors in my mind to things that I had never seriously considered. There were two guys actually having sex and they were clearly enjoying it! I just couldn’t stop thinking about it.
