Paranoia

I have an issue, I have constant paranoia about condoms. I'm not on birth control because my parents believe that birth control means that I'm obviously having sex. And I prefer my sex life to be private. I don't feel that my family should know if I'm sexually active or not. But I have paranoia about condoms. And because of this paranoia me and my boyfriend don't have sex as much as I think he wants. And I feel that my paranoia about condoms isn't needed. What should I do?
