Hi, Jeava,
I think you should go down on your GF before you have penetrative intercourse. If she's a little dry during sex, then what better lubricant is there in the world than the saliva of a loving partner? (God, I wish there was a nicer word meaning "saliva".) In fact, why don't you try & help her to cum with your tongue before you even enter her? Some of us like to be penetrated just after we've climaxed (the feeling as it fills you up when the contractions are still flowing like waves through your body is just
incredible).
Diving is a noble art. If you get good at it (and so long as she's not ashamed or embarrassed to have you down there) you're going to make her a very happy bunny indeed. You don't need a degree to do it. All you need's a lot of enthusiasm, a steel-reinforced jaw and a tongue as long as this little fella:
:fly:
Don't think of cunnilingus as just "foreplay", 'cause for a lot of us girls its more like the main course than a mere starter. What Lilith says is true: surprisingly few women cum from penetration alone. (In the words of Frank Zappa: "There's a spot that gets me hot, & you ain't been to it...") Some don't even like to be penetrated vaginally at all when they're about to cum.
Take your time licking your girlfriend - carressing gently around her labia with the tip of your tongue to begin with; just tickling really; avoiding her clit at the beginning (its often too sensitive if you go "straight for the button" this early); just sweeping your tongue around it in wide circles, teasing open her pussy lips; exploring; getting more adventurous and cocky the more her fingers tighten their grasp in your hair, until your lapping at her like a thirsty dog at its water bowl. Your hands stroking over her thighs, belly, up to her breasts, slipping inside her if that's what she likes. Once you get your girlfriend kinda wet with your tongue her vagina's going to automatically lubricate itself. The more aroused she becomes, the more her clit is going to engorge and swell out of its little hood. That's when you can start directly touching it: tentatively to begin with - test the water before you go diving right in. Once she's really getting into it, you need to keep a strong steady rhythm, flicking the tip of your tongue up and down and round about. (Some say you should write all the letters of the alphabet on her clit with your tongue.)
A lot of guys make the mistake of getting their girl aroused with their tongue but not having the stamina (or decency) to keep it going till she actually cums. There's nothing in the world more frustrating than
almost being
there. You just lay there seething silently, all this energy bubbling up in you and no release.
So, in conclusion, my advice is to lick her till she cums and then fuck like wild animals.
You'll be amazed how different things are when she's naturally wet (rather than from a tube).
Hope this helps.
