Why do guys like it when girls make out with each other?

Most EVERYONE prefers enthusiasm when it comes to oral sex. Men, especially! Remember their penis is their universe. Putting your mouth on their penis and testicles is the HIGHEST compliment you can pay someone. When I do co-ed parties men always say "don't forget the balls" - be sure you are gentle with them but they do like alot of gentle and wet attention there. Be sure to give lots of eye and smile some. It should look like you're enjoying yourself. :)
