MY BIGGEST FEAR

So I have a boyfriend who I honestly love to death. I’ve been with him for almost 5 months. And I’m still super self conscious around him and he doesn’t understand why.. I’m also yet to tell him. I have hs, which is a skin disease that causes sores and bumps under the armpits and on your bikini line. I don’t show anyone and I hate looking at it myself. I want to tell him but I don’t know how nor do I know how he is going to react.. especially when he points out other people’s flaws.. like how’s he going to feel about mine?😪
