I actually slighly disagree with Perna. It could be that he's got intimacy issues from a previous relationship. If he were a woman who had suffered sexual abuse then it might be frustrating, but it would be understandable in that situation that a person might take longer to get "intimate."

On the other hand, Perna is correct that it seems a bit odd that he started off with no intimacy problems and they're only developing now. To be honest, there's nothing more intimate than sex, and he's already enjoyed that with you. It could be that there's something else at the root of it. Very often when relationships fail people apportion blame disproportionally to the other party. I know, because I've done this myself. When I first broke up from my son's father it was "all his fault." Now, years later, I accept that a lot of it was my fault too. Perna is right that you shouldn't take everything he says as gospel.

These issues are so serious that you can't let it lie. If you're to remain a couple, you'll need to work on these problems together. I know it's beating on an old drum here, but have you thought of couple's counselling?
