There are many posts here about similar situation which has prompted me to post.
I can't remember the precise age, but I was somewhere between 11 and 14; I would guess around 12. I sexually experimented with my friend who was 4 years and 7 months younger than myself. I can't remember how it began or how many times it happened, but it was multiple times over the course of a year or so. I have trouble remembering the specifics of the situation, but I do remember roughly what was done. There was some mutual masturbation in which we would also touch each others genitals and some oral experimentation. I don't remember there ever being any penetration but I do remember that we would play a game where we sat on each others laps and he also requested one time that I place my penis on his anus.
At the time I never realized I was doing anything wrong, and in fact didn't give it a second thought until I was around 19 years of age (currently 23).
Even though it was mutual, none-abusive or coercive, I still feel that I should have known better being the elder child and I am now drowning in guilt and a feeling that I don't deserve to live, and certainly I don't deserve happiness.
I have never done anything else of this nature since, having my first girlfriend at 15 and leading a relatively healthy relationship for multiple years. I did however experiment with a younger friend a few years prior who was roughly the same age as me within a year or 2, but that was a lot less adult, being mostly kissing and touching penises.
I have had councilling and medication and have spoken to many people about this, including friends, family and a couple of charitable organizations that deal with abuse, but nothing seems to be working. I am too afraid to end my life as I know my family with be distraught, but I am also finding it increasingly difficult to cope with the situation.
Any advice that can be given to me would be appreciated greatly. Thank you.
