"Why on earth would anyone ever want to give up something that makes you feel so alive and vibrant?"

Because it doesn't make HER feel alive and vibrant. And you can't change that for her, hun.

You can maybe help her change it for herself though....

Just realize that, no matter how confusing it is TO YOU because TO YOU sex makes you feel vibrant and alive....it doesn't matter because you are having to deal with how it feels TO HER.

With some openness on her part toward understanding, she may be able to feel vibrant and alive from sex as well....

But this is yet to be seen and you can only do what you can do.

First step, however, is to ACCEPT that TO HER, it is not something that makes her feel vibrant and alive. And there is nothing wrong with her, she is allowed to feel how she feels, for whatever reasons.
