Lubricant is a good idea! Basically what I can say is let it all come naturally :) ask him what he likes, and try to do things that he likes. You would be surprised how it comes naturally. Second try and keep a condom close by, just in case things get too heated. I know that there is a morning after pill, but still, maybe keep a few around just in case.

You might want to watch your boyfriend masturbate in front of you, so he can show you what he enjoys.

Ok, here is how he will enjoy it:

start making out, and unzip his pants. Pull his dick out, and pour a lil bit of whipped cream on the top of his penis, and lick it off. Then, spit on ur hand, and just keep rubbing. Private messege me for more info! :d

The fact that you asked how to start sumthing like that out makes me think you are young. If you havent gone farther than making out with your boyfriend your not gonna ask the guy to masterbate infront you. In my opinion and you dont really wanna get too kinky the first time you do this...

It comes naturally...When your making out just slowly move your hand towards "that area" rub it gently threw his pants for a while and then unzip and give him a handjob.. I usually start off rubbing the penis softly and gently with just my hand, and then use some kind of lubricant

good luck ;)
