Why don’t I feel anything?

I think About a week ago I received head from a guy I been talking to. I really like this guy and we have a connection, but when he went down on me.. I didn’t feel anything. This is my second time getting head and not getting off on it, and honestly it makes me feel weird. I never masturbated before or had sex because of the pain (I always chicken out) is there any tips for this? Is this normal? I really want to feel this “ pleasure” and I’m scared I will never.🤦🏾‍♀️
