I don't think any sexualized comment is appropriate from a therapist, including comments on a client's physical appearance or how they please the T's senses. Even just checking out the client visibly. There is also no therapeutic reason for those things to be said. I've heard that some Ts think it can be appropriate to comment on the client's improvements in appearance to inspire, for example, a depressed person or someone with low self-esteem, but I think it can be expressed in different ways that don't have confusing meaning. If nothing else, sexualizing therapy interactions (even in subtle ways) can be distracting from what should really be the focus.
