Will people judge me if

I get a sperm doner through IUI and I’m 24 years old? So I made a decision of not being with anyone anymore, I’m good being single for life and having 2 kids. My last relationship was 3 years with this guy I thought we were going to last. Broke my heart now I don’t I haven’t told my parents yet and I’m embarrassed to because they expect marriage and stuff and I don’t want that anymore how do I sit them down and tell them at least my mom also when I get the sperm doner insemination done , will I be able to get it or no?
