Ok, I GOTTA tell you guys this joke. Not the most classy or funny ones, but it fits the topic: A young teenage couple is on their first date. Both of them are virgins and barely know how to kiss. They start making out and the guy asks the girl to give him a bj. She refuses saying how gross it is. No matter how he begs and pleads, she doesn't want to do it. So he asks her for a handjob. She has no idea what it is. The guy explains to her that all she has to do is hold his penis in her hand and shake it like she'd shake a bottle of juice. So she starts shaking it and the guy is going crazy. She's shaking it harder and harder and the guy is about to cum when his face turns all blue. When he can't take it anymore, he screams:"Take your damn thumb off the cap!"
