For me, it was a three step process. The first step was when one summer when I had my then-girlfriend staying with me. We were going at it pretty hard and heavy one day because we were young and horny. After two very nice rounds, we started to work each other up to a third round. When I went to enter her, she found she was too sore from rounds one and two. She started to give me a handjob, but honestly, she wasn't the best and she knew it. She said I should take over and feel free to cum on her. I had seen a couple of lackluster pornos at that point and found the external cumshots always a little silly. But there she was, offering her nice perky tits and tight stomach (I don't think using her face crossed either of our young minds). I came on her and thought she looked fucking sexy as hell with my cum on her. From that moment, I seriously loved the idea of cumming on a woman and seeing her with my cum on her. It was sexy, intimate, and with me, usually involved breasts (I'm a real breast man).

The second step was actually a piece of smut I read. It mentioned the idea of a facial (I hadn't actually seen one in porn to that point). A husband and wife were going to have a threesome with another guy, but unlike most smut, they were actually going to go out on a date together first. The two men "decorated" the wife's face before leaving for the evening. I thought the terminology stupid, but the image would not go away. I broached the idea with my girlfriend (later to be my wife) and it was clear it wasn't going to happen. I dropped the subject for over a decade.

The third step was only a few years back. My wife and I were fucking on Christmas eve. It had been a rough past few months in our lives in general and we were both trying to please each other as much as possible. I took a risk and told her that I had never been able to shake the idea of cumming on her face. She was quiet for a moment and then told me to do it. I did and it was amazing. And I was hooked.

We don't do it often. She isn't a fan and consequently I don't ask unless the desire has just become undeniable. But I think she looks fucking hot with cum on her face, and it had a side benefit I didn't expect. I have always found my wife attractive and pretty, but giving her a facial really sexualized her face. When we haven't done it in a while, she can seriously give me a hard-on just by smiling at me.
