Here's my question. I discovered that my boyfriend keeps pornographic magazines. We have been going out for 6 years. Much of that has been long-distance, but we have lived together for the last year. Since then, I've also noticed that he only wants to have sex after he's spent some time with his mags.
Human nature is full of hypocrisies.
It is normal for you to believe that everyone is free to do what they want sexually, AND for you to want only certain aspects of sexuality in your own relationship. From your letter, Alice guesses that you are still feeling the initial disbelief of finding these magazines, and that you haven't yet approached your boyfriend about it. Once your rage has subsided, pick a time to begin a conversation with him. It's unrealistic to ask him to give up his fantasies, but it is realistic to ask him to separate those fantasies from the reality of your sex life. If you can't live with something like this, then you can try asking him to give up the pornographic magazines altogether, but know that you risk the relationship.
