I don't watch porn, but I have no problem with other people watching it. My girlfriend sometimes watches it, but it doesn't harm our relationship. I really don't care if you do it. You can talk about it all you want, but it still won't bother me.
Viewing porn doesn't mean you're interested more in watching some fake internet sex than you are interested in your partner.
I am homosexual. A lesbian, actually. If you have a problem with that, then it sucks for you. It's not your problem. It's not even a problem. I quite like it this way.
