I have been in a monogamous relationship with my boyfriend for almost a year and a half.  We're both pretty shy people, but of the two of us I'm definitely more upfront about things in our relationship - especially on the sex side.  I have the higher libido (we have sex pretty much as often as I'd like), but I'd like to be able to talk to him about sex more openly.  I'd love to get feedback on how things feel or maybe even goof around a bit without putting too much pressure on him.

We might be going long distance in a couple of months, so I feel like we should learn to communicate these sorts of things better in order to keep things going.

Has anyone had luck with a partner who is shy to start with and then closed off completely when talking about sex?  I'm curious about too many things going on in his head, and am open to ideas.
