V-Card

So I'm really insecure about my body, which is really ironic because im a swimmer and u have to get fully naked to change into your suit. I change in the stalls instead. I don't even like my mom seeing me naked or just my boobs in general. So when I lose my V-Card I will be really shy about being naked in front of him. How do I deal with that? I'm really nervous about that part mainly 😳
