Welcome to MS.
That being said, you are not alone in your struggles with same sex attraction (SSA). The experience of childhood sex abuse distorts our normal sexual development, and that shows itself in all sorts of ways. Sexual confusion is just one of them.
Recovery starts with breaking the silence about what happened. You've already taken that step. You may find other issues to deal with in the process. In the meantime, read the posts here, and write some of your own when you feel able to. MS has been a huge help to me in recovery, and I hope you find what you need here.
"Suffering was the only thing that made me feel I was alive,
Thought thats just what it cost to survive in this world,
...now I haven't got time for the pain... " -Carly Simon now 67!
