Pregnancy Phobia and My Family Finally Accepting I'm Not Giving Them Kids

The title!!! I (21f) knew I never wanted kids as a kid myself, and that I'd always say I'd adopt instead. My childhood and teens were filled with various "oh but what if your husband wants kids" and I'd get laughed at for saying then he can find someone else.

Recently I've developed a real phobia of pregnancy. For the fact that I have no other issues, I can't have fun time without pain due to how bad my phobia has gotten lol! My mom told me to get an IUD to help, and I humored her and got it (I knew it wouldn't help but I like the benefits of being on birth control and I think it'll get restricted in the U.S., so I was like might as well). The fact that I still can't have smex without pain after getting the IUD made my mom realize that this isn't just me not wanting kids (which has always been true) but a legitimate phobia of pregnancy.

Anyways, I soft launched with my parents that I plan on pursuing getting sterilized (told them because I want them to be aware that I'm getting surgery in case anything goes wrong and they need to make decisions), and it's finally not met with any pushback or what ifs. Ofc I haven't talked with my dad about my private life, but my mom has always been a person I can talk to and I have a feeling the information got passed along. I'm annoyed though because it feels like they're finally accepting of it because it's impacting my boyfriend (let me tell you it's not), not that it's for me.

Subtle sexism but I'll take it at this point.
