First of all, Give yourself a break, you were very young and couldn't possibly have really known what you were doing.
Believe or not what you did is more common than you think. I'm not sure about the family member part being common but definitely two boys experimenting with each other is.
When I was 14 years old, I slept over my friend house and we had stolen 4 cans of beer and a pint of Vodka that was half empty, being young and zero tolerance to alcohol we both were pretty drunk. When it came time to sleep the subject of girls came up, and us both admitting the talk of girls got us hard. He sat next me on the bed and began to rub between my legs, as much as I wanted not to do it, either being drunk or the fact it felt good, I didn't stop him.
The next thing I know he pulls down his pants grabs my hand and placed it on his penis. This is the part left guilt with me for years. He was a year older than me but much more developed, I remember thinking he has a man penis, much bigger than mine and twice as thick. I was your typical 15 year old but my friend on the other hand was at least 8 inches long and very thick.
Long story short he ended giving me a ** and stroke his penis.
The next day I woke up hungover and very confused thinking am I gay? You have to understand in the early 80s in my city being gay would make me a target of people.
I never stayed over his house ever again and made him promise never to mention what happened......
For years I carried the thought of how I allowed it to happen and worse still I was fascinated with the size of his penis.
It wasn't until I did some looking on the internet did I started reading story after story of straight boys and girls with similar stories about how they had a sexual encounter with the same sex.
I read a study done by Boston College that estimates 20 to 30% of people have had same sex encounter as a child. It doesn't mean a person is gay, even though some turn out to be but that had little to do with their experience,
I understand with you it was a family member and not a friend. The fact remains you were much too young to understand what you were doing and if you still don't have thoughts of being with your brother. If I was you I would chalk it up to youth and not knowing any better and go on with your life
Wow, this is really a pretty intense question. I think you need to get some kind of counseling or psychiatric help. They may be able to determine whether these things actually happened or you just imagined them. I think this is outside the expertise of anyone here, unless there happens to be someone reading who has experience with psycho-sexual counseling. I hope you can get some help & get this issue resolved...
