I personally don't care what any of you think. I am entitled to my opinions as are you. I have felt very supported up until this point and WON'T be returning.
Heather, if you read this, I want you to know that I hear you. This was triggering for you, and if I read your posts correctly, you also kind of wonder if he didn't do this on purpose. In other words, you are so upset that you can't see how anyone would not be upset and therefore, he intentionally upset you. Nobody has been willing to acknowledge those feelings from what I see above. I'm not judging them. They were trying to show you another way his behavior could be understood, but from my experience, you need to be hear and understood first and foremost before that stage can occur.
Yes, you asked for information; but no, you didn't ask for graphic images. I understand. A boundary was crossed. You have every right to feel what you feel. No matter what his intentions were or his lack of sensitivity or whatever, your feelings are real; and honestly, I would perhaps feel at least a little weird about it if I were you. I wound question someone's motives. Sure, it's his hand, but I wouldn't show you all a photo of my labial stiches after giving birth. Nobody wants to see surgical stuff. Not unless it's your area of interest.
Furthermore, I don't think you should leave the forum and this is why: How do we know that something we've said hasn't been a trigger (unintentionally) for someone, and they never said anything? This was a photo, not words but on another level, we are none of us perfect.
Have you never upset someone in your whole life, by just being to blunt or honest? I think what he did showed a lack of social skills, but we all lack social skills from time to time. Maybe he is on major painkillers? We can give him the benefit of the doubt this time and we can validate each other, and we can come back another day and give each other the support we need so that we can grow and overcome.
