That you for your supportive words - I also wish the same for you.
The fact is, that in the state of America I was in, a 16-year-old cannot consent. It is sometimes frustrating to think that if the relationship had occurred in Britain or in 2/3rds of the states, it would have been legal (some states set the AoC at 16 or have a close-in-age-exemption of 5 years, which would have my relationship and, indeed, your own) but the law is the law and doesn't allow much wiggle room.
Morality is a little different. However, even in spite of the law, I *do* think my relationship with my ex was inappropriate. She was simply too young for a relationship with someone older than herself and I believe she was confused about what she wanted. Towards the end of the relationship she was no longer wholly comfortable with being intimate and, I believe, acquiesced to my advances, rather than enthusiastically consenting, as she had done in the earlier days of our being together. The one time she told me to 'stop' I did so and we never had intercourse without clear verbal consent. However, one time (which I have recounted in other threads, so I'll keep it brief here) I touched her in a violatory way after she had said she was just in the mood to cuddle. Texan law would make no distinction between that act and all the times that were enthusiastically consent to, or indeed initiated, by my ex, which does seem wrong - basically, if we had started being sexual IRL just a couple of weeks later, none of the above would have been illegal (since there was no threat, restraint, intoxication or force), even though 'sex' in our relationship covers a spectrum from the emotionally positive and enthusiastically agreed to, all the way to the emotionally negative and unenthusiastically acquiesced to. I find this confusing as I feel I should experience legitimate guilt due to the latter, but far less guilt over the wealth of experiences that seemed very positive and healthy, in spite of their illegality.
So, I do think my ex probably regrets the relationship - however, she has made it very clear that she does not feel traumatised or consider herself a victim of child abuse. Rather, that I became a pushy jerk and it made her really uncomfortable. For her, that's the extent of what happened. She is no longer hurt and had explicitly states that she feels that I no longer owe her anything. She's long moved past the relationship.
I told my story on a feminist community online and got the following (edited for brevity because the poster discussed some intimate stuff that isn't so relevant here) response:
Don't bother your ex with this any more, that's one really important thing you can do for her. I'm assuming that turning yourself in to the authorities would involve you telling them who you did it to, which would mean she would be involved when she doesn't want to be, and she's told you as such, but I kind of wish you hadn't asked her and just had left the whole thing alone because now you are making her think about what you should do and that's really not her responsibility ... If you did turn yourself in I doubt you would get charged with any crime anyway because convictions are really hard to get due to a lot of factors (like the fact that most people would probably think what you did was ok, even if you now don't) and I bet part of you wants that because not being convicted would make it seem better, like you didn't actually do anything wrong. But that wouldn't be true.
As for the girl who assualted me, we are still in touch (we were friends for a long time, I care about her because I never got out of the habit of doing so, and I want her to have a good life, as long as its separate from mine. Note, that does not apply to how anyone else should or does feel about their abuser, my story is my own and their stories are theirs, so please don't use my saying that as an indication of how any other survivor feels), but if she ever came to me asking what she should do about the assault now, I would be livid. I don't want her to make it about herself. She was selfish in touching me when I didn't want to when we were teens, and it would be her being selfish again to do so. I hope to god she never, ever does.
Finally my advice to you: in the UK Graham Norton runs an advice column in a newspaper, dealing with relationship and family situations, and his advice to people asking him whether they should confess that they cheated on their partner is always no, don't tell them. Instead, he tells the letter writer that their guilt is their punishment that they have to live with, rather than hurting their partner by telling them. I'm not 100% sure I agree with him about cheating in relationships, but I really think his advice applies in your situation- you have to live with your guilt. And you must not make your ex deal with any of that guilt, or any other sexual abuse survivor.
Now, my ex doesn't seem to identify herself as an abuse survivor, so I don't want to put words into her mouth, but at the very least it is the case that she was the victim of my unwanted sexual advances late in the relationship and found herself in a position in which she could not easily say 'NO' since she was young, confused, and anxious not to hurt my feelings through breaking up with me. In your case, there is no indication that the 14-year-old was whatsoever unhappy or uncomfortable with what happened between you. I do reckon that the age difference was veering towards the inappropriate and that the law remains the law (although it is worth remembering that there are many, many unjust laws in the world, such as the criminalisation of homosexuality in Russia, or stoning for adultery - I don't think that these examples are quite the same, but even so,
the law isn't always the sole arbiter of truth and values) however I also think that
nothing would be helped by you going to the police and that you really ought to cut yourself some major slack. You sound like an earnest and contrite person, who likely hasn't hurt anyone and, though you broke the law, the small age difference would mean that you would probably have been given a suspended sentence at worst. I hope you can see the distinction between yourself and the celebrities on the news, because you're really nothing like them.
As for myself, I have to learn to deal with my guilt and continue living despite. I've certainly learnt from my mistakes, now put lots of effort into helping out the British charity Sexpression and generally doing a lot of voluntary work, and make sure that my girlfriend is always 100% comfortable with our sexual interactions, which tend far more toward cuddling, than anything else. I think that even if behaviour or a crime carries a great stigma, it is worth remembering that you have not destroyed the life of anyone else and, as such, you have a right to life. It may not always be happy or free from guilt and anxiety, but it can still be a life worth living.
Stay strong
