A question for the men.

I guess it is time for sex therapy.

I literally cannot get hard when I'm around her. This was not a problem before, we went through a HB phase and afterwards throughout reconciliation we continued having sex.

But it feels like the more emotionally close we get and the more I understand her and the more I share myself I lose the ability to desire her? Is there some "Madonna/wh*re" thing going on? My WS suggested this, but I don't actively think in those terms and I still think she is incredibly attractive, so I don't understand why this is happening to me all of a sudden.

I don't feel very nice turning her down when I know it is a very big leap of faith for her to take the initiative. And I also don't know if this is normal for me to feel or is something wrong and I'm just not able to tell what it is. Did anyone else go through something like this?

Edit: WS thought it is important I also mention that we do engage in other forms of intimacy like cuddling and making out and I experience no triggers during it. It is specifically penetrative sex that I struggle with.
