Egads, man.
1) When you're on testosterone, your vocal chords will stretch. You won't even be CAPABLE of saying "eek" anymore.
2) There actually are appropriate channels for males to express affection to one another. You will adjust. It's like learning a new language. It's hard to teach in a class, but it comes naturally if you're around it all the time.
3) Here is a little known secret. It's something that you only really come to realize after a few years of experience, but your parents have probably told it to you since you were a toddler. If you were like most children, you probably didn't believe them, but it just happens to be a fact. No matter who you are or where you come from or what you stand for, people will respect you if you bear yourself with self-confidence and express yourself in a manner that suggests self-respect. Iron your clothes, keep yourself well-groomed, stand up straight and tall, and enunciate your words. It's pretty straightforward.
