I'm an incel in the sense that I'm an atheist and most of the single women in this area are Catholics who aren't interested in relationships with non-believers. I had a very satisfying relationship with an atheist woman during the early 1990's. We separated on friendly terms when she decided to move away on account of her career. By then, I was in my 50's and no longer interested in pursuing another relationship. I've been without a sexual partner since then and it hasn't bothered me.
