Basically, you're asking me whether NOT talking about an intimate relationship means that you and your lover are opposed to having a more robust relationship. I think you need to ask yourself why YOU'RE not talking about what's going on. Are you afraid that you'll scare this guy off? Do you want more? What do you need from this? If you need more from the relationship then don't be afraid to say so and be ready to deal with the consequences. You might lose the sex, but having self-confidence is far more valuable. If you want something, then go get it. And there's nothing wrong with the way things are now if you're enjoying yourself and using protection. But if you want more, then you need to express that.
