Be slutty and show him what you want from him.

you should totally slut out over that cock, make sure to suck it and feel how hot the head and shaft feel in your mouth

just go for all the things you want to do. thats what idid with my first cock

Relax and enjoy

No need to be subtle. Don't worry, nothing you'd do will be something the guy hasn't already done or wanted to do or jerked off to in porn hehe

If you're nervous, bear in mind - if you're getting together with a gay dude - straight 'experimenting' guys are #1 for desirability among gay guys - the holy grail, a hot commodity. Gay gays would kill to have a shot at a straight guy. Always suprises me that some straight guys aren't aware of this.

On the other hand some gays out there aren't into it because they say the inexperienced ones aren't good at sex and don't know what to do. But these are a minority.

Life is short. I remember when I was your age, shy and very nervous! Now 65...Do what you want to do. I wish I had! Have some fun sexually! What society says is sexually allowed is just a bunch of BS. And totally different between this World's current society's. And totally different throughout history... It's all the religious zealots, political dopes, lawmaking 'idjuts' putting their Victorian sexual beliefs on YOU! Because they can. Just be careful and picky about who you do it with...

Thank God we had a boys locker room in gym class in school! Saw plenty! It was an all male revue for me!
