I know that I have no interest in being a father. I would be a terrible parent. I am well aware of this. Therefore, even when I reach that point in a relationship where I would be willing to endure the consequences of the sexual act, I would prefer to avoid them. Therefore, after discussing the topic with the woman, I do engage in the use of contraceptives with the intent of preventing a potential pregnancy, but with the knowledge that if it doesn't work, I'll be marrying her and raising that child with her to the best of my ability to do so. Unlike many others who would suggest "alternative" methods of avoiding the responsibility/consequences I believe that one needs to own up to them and deal with them IF/WHEN they occur.
