It's a fair question to ask, as I don't think it's talked about openly.
As a child, I had no clue of what sex was until later, or that it was supposed to be enjoyed. Imagine how you may have felt your first day of school, and how vulnerable you may have felt. Now imagine someone trying to get a sexual reaction out of you in that state, with no regard to your enjoyment. That is basically molestation...which is too soft a word.
Now imagine it being a grandparent who is perpetrating this, and that you are supposed to trust them. Trust for people is destroyed, as life becomes one big lie to avoid humiliation. There is no pleasure.
Once I was older, my family moved away, so I didn't have to deal with that person anymore. The next one was a school principal. I was just one of a few hundred boys he enjoyed, and was able to stop it after the 4th time. Parents were involved and threats were made. The guy was later convicted. I tried coming forward about it then, but was not popular, so it resulted me getting a lot of people angry. One boy who came forward had his house burnt down. The public supported that principal.
The third person was when i was 16, and was a school teacher. She decided to start things in a prop room in my school's auditorium. Didn't like it, told her to stop, and went forward about it. That caused people to think i was gay, and I got into a lot of fights because that area hated gays.
The 4th was when I was 18. A friend I trusted. She drugged me, and I woke up with her on top. It took a couple minutes, but I realized what was going on, and i threw her across the room. She weighed over 300 pounds. I was 190 then.
The big takeaway is that none of these people ever really cared about me, and wanted only to please themselves. I was, essentially, a sex toy. The effect of that was to destroy trust in people, the legal system, and society as a whole. It has taken years of work to mentally rebuild, but fragments remain, and those are fragments of control. I can do whatever I like in life, and am now happily married with a very understanding wife. Sex is still a touchy topic and something I try to avoid.
Another way of putting it would be, what if, during sex, the other person did something you didn't like, but you had no say, or physical power to stop them? What would you do?
I usually was a horny kid from about age 8 onward, but enjoyed my solace in it. People were just...complications to be avoided. That thought grew into a more antisocial view, and I often quietly hated people. If in a fight I would do my best to kill the person, and when I couldn't I would break bones and joints, so they would live with a bit of pain each day, to understand in a physical way how I felt internally.
Miraculously, suicide attempts failed, in completely illogical ways. One example was a gun I had shot for years that never jammed....it did the day I tried to use it for suicide. I took the shell out, and no jamming of the trigger again. That shell was later used to kill a deer so that was not the problem.
I know this has rambled, but I hope it sheds some light on things. It's good to discuss it now and then...mto really see that iI am not who I was.
