I wouldn't think that you'd be any more "weird" than a lot of us. Our CSA left us with a whole bunch of strange thoughts and feelings, all crashing into one another.
Guys check each other out as they would the car the other guy drives. Put sexual attraction into the equation and you've got another ball game...sorry for the pun.
Who abused us, what were they interested in, what did they get us to do. These distasteful acts put some awful ideas into our heads.
Like LCB says, talking this stuff out with our therapists is paramount to our recovery. It is only in the therapy session where we can see that these are not life condemning thoughts, but residual garbage with which we were left; thoughts and feelings that haunt us until we work them through.
Good luck, Liam, and don't beat yourself up too much.
