"Only if it's women's 😉"

Please tell me I'm just being hormonal and overly sensitive because I'm pregnant. we're sitting around with my step sons (11, 16 and 19) and wondering what to watch. One of them suggests tennis and my SO says "only if it's women's haha.." He has a history of talking about other women's (such as on TV) appearances at family gatherings and in front of me and it makes me feel uncomfortable. I feel like it's disrespectful and inappropriate. I'm hoping someone can just tell me I'm a giant prude?
