How can i overcome being embarrassed by nudity and sex?

Part of growing up: Not everyone has an easy time with this, though we all experience it. If you have the idea that you're unattractive, do what you can to look better and perhaps talk with someone who knows how to treat body dysmorphic disorder. And don't feel you have to rush romanatic love -- the best people let it take its time, and save themselves for someone who may be that one special person.
