The Whole Package 😧

Am I the only one who is uncomfortable with sex, tampons, nudes, sexting, blow jobs, etc.? It just makes me feel awkward, and it gives me chills. I'm hoping I'm not the only one. It's just uncomfortable for me. I really don't know why, I mean... I have trust issues and anxiety, but other than that? No past filled with sexual abuse or harassment... What can I do to become more comfortable with all of the above listed topics?
