AIBU to tell my friend her partner sent me an explicit photo

Are you 100% sure this wasn’t a mistake on his part? If it was me, I’d reply saying WTF? Why have you sent me this? and await his response. If he’s shocked and embarrassed then fine, but if he’s creepy then you should tell your friend asap.

I’d watch the earlier message/video he sent in case it has a bearing on the last one

I would reply something bland like "this is an unexpected message" with no emojis. Then if he replies asking if you like it etc then it's total proof he's a bloody creep and he did it on purpose. Obviously you reply then saying it's unacceptable. Then tell and show your friend.

This to me sounds like you are being quite nasty to your friend as if they were in it together and I don’t think it would make the friend feel grateful to have been given any considerate options receiving this.
I agree with PP childish insults are not the way to go here.

I said i would be, not she should be.

Yes, it’s a crime now.

OP has explained that it was sent via TikTok.

Why should his partner be ashamed? It's not her shame to carry.

Men know we don't want their disgusting unsolicited dick pics, he's getting off on the shock value.
It turns out my ex was sending them to lots of women, when it came out it was bomb after bomb.
I have a young daughter too and he's only allowed supervised contact with her now.

I think it's absolutely abhorrent when a man sends a picture of his privates without consent. Just something about it feels so forceful, violating and wrong.
You had no choice in the matter. It was just there when you opened the message and saw it with no warning. Vile man. If it was my husband i'd he so disgusted and ashamed he'd done that and put you in this position. Judging by what you've said though, she won't say or do a damn thing about it.

I’d add in your comment to her that she might want to sort it before he starts doing it to his daughters friends so that it doesn’t get swept under the carpet and point out that next time it’ll be the police and there won’t be another warning.

Good luck, Op.

If you don’t have a friendship with him, or any sort of texting relationship then it seems obvious this is a mistake that it sent to you.

Why bother insulting his penis there is no need. Just tell her what happened

It’s most likely that the dick pic wasn’t meant for you and he’s messaging other women on tok tok. Hence the mistake.

But yes she needs to know. You could also speak to him and make it clear to want zero contact or you’ll report him.

you could already report him on tik tok itself.

Do not forward the sick picture to her. It is an offence. However you need to let her know and if she chooses to ignore the matter say goodbye to your friendship.

If this was a text he’d be able to work around it far better by claiming it was meant for your friend and he’d accidentally sent it to you. The fact it was TikTok makes your life easier imo, he can’t claim it was for her because why would he send it on there of all places? The best he could do is say it was for someone else but it doesn’t make his case much better.

The guy is pretty baffling. Did he think you’d see the almighty dick and want to jump on it and betray your friend immediately? I’d love to know which planet he’s from.

Telling her would be the first thing I do today. Not sugar coated. Isn't this a crime now?

Yes, you have to tell her. So sorry that scumbag put you in this position.

You absolutely have to tell her. I’d honestly be livid to have received this and would be letting them both know - her so that she can dump his scuzzy arse, and him because he’s grim 🤢.

Just as an add on as I've read others responses, men know women don't want dick pics. He's getting off on the shock value and power of it.
Tell her and just be straight. Most friends will believe you. If she decides to stay then, so be it, but she deserves to know. Would any of you want to be with a man like this? You wouldn't. She needs to know.
I never doubled my friends for a second. His face when questioned said it all anyway.
I know it'll be difficult OP, and it's an awful position he's put you in, but if you leave it then the heartache is just being prolonged.

Tell her ASAP. My disgusting ex husband was doing the same thing. This is more about power and control than anything else. I was unaware as my friend didn't mention it until we had a falling out a couple of years later. I really wish she'd have told me straight away but I never was angry at her, because she was put in an awful position, I was only angry at him.
It turned out my so called lovely husband was capable of a lot worse. The dick pic was the tip of the iceberg.
Does she have children?

This is the safest option.
