Any of you guys self conscious about this?

Someone I kinda have a thing with has been tryna get in my shirt but I’m SOOO self concsious about my nipples, this might seem so weird but i feel like they’re huge and I’m embarrassed. Is this dumb? I don’t know what to do ... we’re not actually together so it’s not gonna be like “Oh well if he loves you he won’t care” , that’s not the case here.
