Similar here, similar age. Wife won't talk about sex at all. Then I found that I could just start doing more without saying so. We started watching porn together and things got better. While watching I can get her to say what she prefers to watch. Nothing seems to be too extreme, some things are just not preferred.

So then I started slowly into the path of doing things that she said she didn't want, all is good so far. Never has stopped anything. But I only advance a bit at a time, always likes it.

She is not embarrassed, just doesn't talk openly about it. She did once say that I could fuck her any time that I wanted to, then didn't. So then I start the porn when I want to and then it's good to go.

Since you know that your wife watches porn, you can just start with that. She could feel bad until she gets into it. You might start from sexy romance movie and go to soft porn first before the main show.

Another thing is helping with hair removal. If she shaves, that a chore and is not good in a few days. Try pulling her hair out with tweezers. This takes a lot of time, and many sessions, a problem? This was not my idea, my wife handed me the tweezers and set me to work.

I know from previous relationships that girls are up for things that they don't talk about.
