I agree with you, I just feel I've tried several times and always end the conversation feeling more frustrated. I remember once I got mad at him, turned my back and he was content not talking to me for over an hour until I talked again. I know it can sound petty too, but I just feel he should be able to talk about this type of stuff after 3 years. We always end up with me telling him he needs to break down that wall and him agreeing, but not really trying anything after that.
I know if I ask would you like to try this etc, I won't get a passionate reply, it will be like an "ok, if you want" and I just get annoyed that I don't know if he wants to or is feeling obligated to do it because I asked?
I know I have little confidence too. I would like to initiate a conversation and feel like we took a step together, or at least get a reply that wasn't so lukewarm from him. I've asked did you enjoy that, did you like how I did that and I get such an awkward "yes" from him that I can't really build up much confidence. I thnk he enjoys the sex, he's just so bad at talking about it.
