I don't know what you mean. You mean women controlling when and where they have children? No, I do not think this is a problem. As for what you feel, it is irrelevant. While your sperm may have contributed to it, it is the woman that has to deal with the consequences and, therefore, has the right to do whatever she feel she must do. In other words, you are just a spectator and are of little importance to those actually involved in the situation.
Fatherhood is an important role. I'd much sooner raise a child alone than have it aborted without my consideration. I mean, for all intents and purposes, I'm pro-choice, but on a peronal level I feel there's much more to it than a "medical procedure", and the father certainly loses something in the child. My daughter's mom actually made an appointment to have an abortion (without my knowledge), but thankfully she didn't go through with it.
