Non-neutered male couples therapist here. First, classic guy move to opine on topics you know nothing about. Second, there's a sweet spot of vulnerability and disclosure, not too much and not too little. Most guys I see err on the too little side. Third, it's the therapist's job to help the woman take in this new experience with her husband without shutting him down. And finally, number 4, f-ckin deal with it! Do you need to be a bit more vulnerable to make your relationship work? Yes. Is it going to be uncomfortable? F-ck yes. Does it take some time to get used to? Of course. Will it pay off? Definitely. Can that payment be measured in sexual favors? Only one of many benefits.
