Is it normal i'm a 21 year old, friends with a 12 year old girl?

Hmmm. A 21 year old Trans man with a 12 year old girl. That just weird. Sorry.

A 21 year old man whether trans or not is just not right even with her mom's permission is just wrong on so many levels. She probably had not become aware of her sexuality yet but when she does and you and her are still friends I can see trouble ahead.

Since you don't think of her in a inappropriate pedophile type of way it's fine

It sounds like you only met once and you were nice to her, which is totally fine. Parents do have a right to be distrustful though, even though it sounds like your intentions were good, it's just that there are a lot of weirdos in the world...know what I'm saying?

Ye you're in a tough one. Honestly I think this is perfectly fine. You're going to get a hell of a lot of dirty looks though maybe even some comments if people find out you're not related. You're kind of fucked because everyone's on a witch hunt for pedos, it doesn't matter that you're not, you're a significantly older man chilling with a little girl. I say keep doing it if you want to, tbh if enough people did and nothing happened then it would give people mroe faith in humanity generally. But I think it's probably no going to be worth it, I reckon society will come down hard on you even though you're intentions are benign. Also on a side note do trans men generally like men or women?

Leave her alone until you talk to the police and get permission.

I se nothing wrong with this,f the mother is okay with it. I would however come out to them about you being Transgender. If they are truly willing to be her friend is in a big brother type of thing, I think it's awesome.

12 will get you 30

I don't quiet agree with the last part because it is a fact that it's usually old males that rape girls and it's find for people to be cautious. But I think it's normal for you to be friends with her and also very cute

I think it is ok love. Respect her and dont do anything stupid, and all is okay :)

A thought an acquaintance can be friends even if you'll never see them again.

About being friends with someone much younger, it will generally look but at times it can be ok. I've always been able to relate to children really well and they always are drawn to me. In my last neighborhood there was a girl who was I think about nine and I was in my 30s but I look younger. I'm female. She was an only child and she always wanted to come and hang around with me. It was basically like having a little sister/big sister. She liked pets and she liked nature like I do so she would go on walks with me and our dogs and say hello to my cats and we would do outdoor things. Of course as an adult I would sometimes get annoyed with her coming around so much. Certainly there was nothing sexual about it and her parents were fine with her coming to see me. There can be many different kinds of friendships, but society does tend to view things a certain way and also what OP said - it's looked at worse if it's a man befriending a younger child, either a boy or a girl I think.

It shouldn't be such a problem but we live in a world where monsters hide in plain sight. Predators exist and are on the prowl for our children and for us adults too. its just weird because what do you have in common with an immature 12 year old? you did something nice for a young child but its not friendship and its weird that you are thinking that it was. just my two cents.

Personally I think it's normal to be friends with anyone who wants to be your friend. But I must agree that you're putting yourself in a very dangerous position. Is it worth it? Don't you have other friends your age? You must weigh your need for a 12 year old friend against the possible negative outcomes.

Find friends your own age, regardless of gender preference, etc. You're 21 and of legal age; She's 12, and all kinds of a minor, no matter how cool or mature she may seem. One negative word or accusation from her, and you're butt is behind bars. Maybe don't go to pizza places to meet women?

if you send her a Text and her parents call the police its a jail time molestation of a minor charge. and all they have to do is prove you sent a text. thats why children are called jailbait

I think it's weird. Yourself intentions were genuine but no one knows this and that definitely wouldn't have let you pay for food. It's just more of a stranger danger thing and the 12 year might now be more susceptible to greeting strangers.

You did a nice thing for a child, that hardly makes you friends.

...why on earth did you feel the need to mention you're trans? Why do you people along with special snowflake people ALWAYS feel the need to mention it? It has absolutely nothing to do with your question.
