not Comfortable in my own skin

I bought my first corset ever and when I tried it on, I felt sexy, but weird too. I was raised in a super conservative family, where my parents barely talked about sex and if they did, they made it out to be disgusting. I want to feel sexy and comfortable in my own skin, especially with my husband. It puts a real damper on our sex life when I don't even believe I am beautiful or sexy. The corset helped a little, but I still feel almost guilty or dirty. It's probably so dumb. Does anyone have any tips? Self-confidence booster?
