Anxiety with moving forward sexually with boyfriend

Hey guys so this is me posting asking for major help bc I have no idea what to do. I’ve been with my boyfriend for a little over 4 months (we just had our 4 month on Jan 18th) and he wants to do stuff more sexually. The farthest we have gone is made out, I wanna do more stuff too but every time I think about it, I just get so anxious and I’m only uncomfortable with the idea of how awkward it will be. Sometimes when I’m at my house and try and think about it, I’ve had panic attacks. Like I want to do more stuff but my anxiety kicks in and thinks “no you have a weird body and vagina and he will judge and tell all his friends” which ik is not the case at all bc I know he is a loving guy and loves me for me but I can’t just get my paranoia to back off. He doesn’t even get off from just him beating off anymore because he says he really only wants me. Idk what to do help!
