what do i do?

so the whole boyfriend thing right now is kinda new and i’m still getting comfortable with him because i don’t hookup with guys, i usually stick with one guy, so i don’t have a lot of experience, but i’m not worried about experience, i’m worried about being embarrassed of showing “me” and being naked in person in front of him, or if he tries to go down there and i end up letting him, im scared of what he thinks or something. Like do i just go with it and don’t think anything of it, every girl has a vagina, it’s fine, or let it get to me and be embarrassed and scared, or something like that, any thoughts or can anyone help?
