ever had something not bad you have always wanted to do but you are too ashamed to bring it up to someone close?

have you ever had something you want to do but are too ashamed to admit it to family and friends? I realized how many things i want to do but i am scared that family will juge me. like if you like death metal but your friends and family hate it, or if you want to be friends with a guy that is much older than you? I realized i have a lot of thoes kinds of things and im going to go ahead and do some of them im fist starting with introducing a guy much older that i have been friends with just friends, everyone else draws the conclusion right away that we are dating but we are not, i hate how people think men and women can not be firends.
