Trust me, it's hard to explain to people who aren't into this kind of stuff. But I can say that it's up to you what you do. See how it works. If he starts to get into the stuff a feeder would do, then he's the best boyfriend ever. But if he doesn't get into it, then it's up to you. Does having a boyfriend who is into this stuff really important? Or is preserving a friendship more important?
