Firstly, I think this comment is completely uncalled for. It is not our place on this forum to bully people when they have feeling and opinions that differ from our own. You don't know anything about this person, how she grew up, what kind of issues she's had with women in her life. Misogyny is a sad thing for many but a gender divide is real and normal for many as well. At least she is introspective enough to call herself on it and recognize that that's a really struggle for her. And on top of that I think this is a relatively normal response in at least my culture. Women have fought so much for equal rights that they have forgotten a certain sense of community amongst themselves and you often see women subconsciously enter into competition with others. Yes this can stem from self consciousness and low esteem, but many will attempt to be unfazed, in control, and normal around those that they perceive in competition with.

Sorry to jump in, but this comment really bothered me.

As for the original statement, I think it would be really good for you to have a conversation with your therapist about what it would be like to talk about sex stuff. You don't have to let him in on any details yet, just feel out the room and see if it would be something you two could come to be comfortable with.
