Homosexuality: Choice or Chance?

I'd question the accuracy of the cool nurse.

When boys enter puberty a lot of hormonal changes occur. These changes will result in many, but not all boys experiencing episodes of spontaneous erections during sleep, during the day and wet dreams.

Every thing I've read and seen says, boys will experience spontaneous erections during sleep and awake starting in infant-hood. Not emissions but certainly erections.
