Is it normal to be uncomfortable with your own fertility?
I find it creepy that (I think) I am fertile. I feel like emitting sperm is like shedding viruses from a cold. It is creepy that it could "infect" a girl. Sometimes I have dreams about quick-and-easily self vasectomizing by snipping the vas deferens with wire cutters (since it is a relatively external organ). In the dream, I then feel better like someone who has gotten over the flu and is no longer contagious.
I don't get how some men find their fertility makes them a "real man". I guess these types of body issues are more common with women who find the idea of being pregnant creepy.
