Forming a trusting relationship with your OB-GYN is important. You need to be honest with them about your medical and sexual history, symptoms, needs, and desires. You also need to be comfortable enough to ask questions and be able to make informed decisions about your health care. You should choose a provider you trust and follow their advice. For many reasons I haven't been able to get comfortable with a male OB-GYN. Mostly though, it's because they don't "get" my body and there are things even your male OB-GYN shouldn't mansplain to you.
Things like how painful a procedure is, because when you are personally experiencing pain, it really sucks to have someone correct you about how you are feeling. The same goes for how a labor contraction feels. Ummm, how the heck do you know? There are also things that are super personal, like choices about my fertility, sex life, and plans to have or not have children in the future. Totally not any of your business, unless I need more information to make a decision. The only things I want to hear from my health care provider about my pregnancy or reproductive choices are facts, not opinions, thank you very much.
Pregnant women already feel judged and scrutinized by everyone for doing the wrong things, eating, drinking, and often simply just being pregnant in the first place. We certainly don't need to feel judged by our OB-GYN and we definitely don't want our pregnancies mansplained to us.
