Sexual matters

Hello im hoping someone can help? i have recently started to see a girl i really like who has chrones. I knew it effected the digestive system but that was as limited as my knowledge went. She emplained to me recently about the more visual effects of chrones which i was a little suprised about.She mentioned growths on her bottom which i felt uncomfortable talking about but at the same time i was pleased that she felt comfortable enough to talk to me about it.
I am a squeemish kind of a guy and i am concerned to my reaction if or when we get intimate. I dont want to judge a person on something like this and my brian is working overtime because i dont know where exactly on her bottom they are and how bad it looks.she is so nice i dont care about sex i just want to be with her but at the same time i know in my own mind how off putting this could potentially be.Appologies if i am offending anyone but one has to be honest and this is not about me its about her as she is the one having to live with it and i may come across as shallow but i need some advice as i am not ready to talk to her about this just yet in detail.
