I'm new here and this is my first post. I happened to discover this place.
I know this topic has been covered many times, but I would like to take it to a different direction this time. More into discussion than erotica narrative.
I am bisexual male 50s married to my wife. I happened to have sex with my dad for 20 almost years. It started in my late 20s when my dad had his shop and I was working for him to support my kids. I was never sexually attracted to my own dad in any way, never thought of having sex with him at all before. It occurred one time when we were alone in the shop and drinking a few beers. Since then, we progressively did more until getting fucked by him a few times. Once my dad retired and closed his shop, our encounters were more sporadic. The last time he fucked me was on new years eve's 2020 at his house, and right before the pandemic there was a brief jerk off between us. Even though I am still married with my wife, sometimes these memories turn me on but sometimes disgust me. However, after 20 years I learned to live with the feeling. It was consensual on my part at least.
From what I read and learned so far, it is more "normal" between brothers or cousins discovering their sexuality growing up but I wonder if there are people like me who started or continue to play with their dads or brothers later in life in adulthood.
Hopefully to have an open minded conversation
