I’m a 26 yr old guy and my girlfriend is 25. We’ve been together for almost seven years, and I’m planning to propose to her very soon. Our relationship is honestly amazing. We rarely fight, we communicate well, and I genuinely feel like she’s the person I want to spend the rest of my life with.
But there’s one thing I’ve been hiding from her for almost our entire relationship.
She has never seen my back.
When we first started dating, I developed pretty bad back acne. At the time, I was convinced it would clear up within a few months, so when she asked why I never took my shirt off around her, I lied and told her I had some allergic skin rashes that I felt insecure about. I thought I’d just wait until it healed and then never have to bring it up again.
Except… it never healed.
Almost seven years later, my back acne is still there.
Over the years, this insecurity has completely taken over my life. During sex, I keep my T-shirt on. At the beach or the pool, I’m constantly making sure she’s walking in front of me. If I have to turn around, I do it quickly or try to cover my back somehow. I’m always thinking about angles, towels, changing clothes quickly… basically doing everything I possibly can to make sure she never gets a clear look at my back.
I know how insane that sounds.
The crazy part is that she’s told me multiple times that whatever I’m hiding, she wouldn’t care. She’s the kindest person I know. Rationally, I believe she’d probably hug me and tell me it’s okay.
But after hiding it for so many years, it feels so much bigger than just acne now. It’s become this huge secret that I’ve built my life around. I’m embarrassed that I’ve lied about it for so long, and I’m terrified she’ll wonder why I never trusted her enough to show her.
I feel ridiculous saying this out loud. I’m about to ask my dream girl to marry me, yet she’s never properly seen or even touched my back.
Has anyone else dealt with an insecurity that got completely out of control like this? How would you handle this if you were in my position? And if you were in hers, how would you react?
I could really use some honest advice.

TLDR I’ve been hiding my back acne from my girlfriend for almost 7 years, even wearing a shirt during sex and making sure she never sees my back. I’m planning to propose soon, but after lying about it for so long, I’m terrified to finally tell her.
