I've always been so confused about sex and relationships.

due to my upbringing I feel these extreme lack of confidence in life. I was bullied and called gay at school. I don't believe I am gay but I don't feel manly or confident at all. I contantly feel worry or shame about my sexuality.

do to religious influence in my life I feel at a loss when it comes to sexual desire. I don't know what to do with it. How do I not feel guilty or how do I handle it in a healthy way?
