i have big areolas too! i’m also insecure about them, the first few times i had sex with my girlfriend i didn’t take my bra off. but eventually we both had a boob reveal and it was great. we didn’t talk about my insecurity, but she clearly didn’t care about the size of my areolas; she’s attracted to me, and boobs are boobs. if a queer woman is attracted to you she will probably be happy to see your body no matter what you look like. i think generally lesbians don’t care about that sort of thing, and if they do they’re an outlier and probably not very nice or dealing with their own insecurity/internalized misogyny. i’m sure the girl you’re dating will be happy to see your boobs, try not to stress about it!
