I was in a relationship with this girl for 6 months and I had known her since primary school. We were considering have sex for a while but we wanted to wait until the right moment (we're both virgins). When the moment came we undressed to our underwear. Then I looked down at her tummy and saw a little bag, I asked her what it was and she said it was her "colostomy bag". I saw that it was attached to her so I looked closer and saw there was a tube going into her belly. The bag had a see-through window and i saw what looked like bag of shit being fed into her body. I freaked and shouted "ew ew ew ew ew ew", i then told her to "get the fuck out of my sight". she started crying but i was too freaked out and in that moment my feelings towards her changed. we got dressed again and she left the house.
She tried to text my for 2 days but i didn't respond, then she got one of her friends to contact me and she explained what it was. Apparently it's a real medical thing called a "colostomy bag" and she has one because she had her bowl removed when she was a kid and so the shit couldn't leave the butthole anymore.
It's been 5 days since that happened and I'm too scared to talk to her. How do I make her understand that I was weirded out by the fucking bag of shit she carries on her tummy!? How the hell was I supposed to know she had her bowl removed? Although I does explain why she had thin hair between the age of 7 and 12.

Should I try and make up with her? And if so then how should I do it? I ditched my previous girlfriend of 2 months for her so I was hoping the relationship with her would last. But even if it did last I don't know how I could live knowing my other half carries around a bag of poo everywhere she goes.
