My partner and I have been together a year and a half but we haven't slept with each other. We are both in our twenties and he has had relationships before but I haven't. I'm ready to take the next step with him but I'm quite shy and finding it difficult to say. He is happy with our current situation so I'm not sure if he even wants to be more intimate but the time feels right to me. I'm worried he will reject me even though we get on great in every other way. I just wonder why he hasn't made a move yet. How should I go about this?
