I know that is a very scary question to consider. I will start with my answer, and try to describe the contributing factors.
My answer to that question is Yes. It has taken a few decades for me to realize and accept, but I think it did. When I was very young, prior to entering into my 'enema era', I used to look at people with a child's view, and liked the ones that were attractive, or fun, or otherwise pleasing to be with providing they were willing to spend time and play with me ( I was only 4, remember ).
But then, due to factors which I have recounted elsewhere and will not repeat here for the sake of brevity, I was entered into a course of regular enemization ( once a week ), augmented as Mum felt necessary with many additional ones for what I am sure she was confident were good reasons, though not necessarily essential. I hold no bad feelings about this, I actually think they did me good. It was the era when parents were scared rigid by the possibility of polio (no vaccines yet), rheumatic fever, and a number of others which have since been 'conquered' by modern medical science.
However, the enemas also got me looking at people from a different perspective. I found myself trying to get a glimpse of their backsides, especially the girls and women, men were big, hairy and scary, and little boys were usually dirty, but women always seemed so clean, and smelled so nice, and I started to occasionally daydream about how neat it would be to see their bottoms unclothed and bent over to receive the enema bulb, just like I got every Saturday morning. Now I was only 5, and knew nothing about sex at the time, but I now realize it was the beginning of my attraction to the opposite sex. So my lusting after the female form originated in considering them as potential enema receivers. Naturally, I NEVER mentioned these considerations or yearnings to ANYONE, as I was certain they would not be considered acceptable. However I was savouring these sights with hidden dreams long before I began to mature. As I approached the age where other boys had started to talk about being sexually attracted to various actresses, girls, and women, I could dovetail my feelings of being attracted to them as well, but I KNEW that enemas had given me a 'jump start' of a few years on all of them, and I smiled to myself...
Oh, I did grow up and get married and had three kids, but my wife, who is a wonderful enemate, doesn't enjoy them at all, but that is another story.
