I've been with dp for 2 and a half years and even though things were quite rocky at times we always had great chemistry. He's worked through past jealousy,insecuritues and together we've got past a time when he cheated. Now things are better than ever apart from the chemistry which seems to have shifted. He rarely trys it on with me and when I start things off with affection whether it be a cuddle on his lap or sex he will turn everything into a giant joke. Just last night we got into bed and I started kissing him and he joked about loads of gross things to do with his arse, made his penis into a character and put on a cockney accent. Basically just acted like he was down the pub with a bunch of guy friends. Every time he does this I'll feel really put off and so many things will be going through my head like if he does it so I'll leave him alone, if he doesn't fancy me anymore and if he did things like that with that other woman.
I've expressed how I'm not into the joking around in the bedroom but he gets defensive and sulks. Can anyone shed light on this or if you've had similar experiences?
