The best tip i can give you is to TAKE IT SLOWLY.
The first time i kissed a girl i was in there like speedy gonzarles. My tougue was all over the place!
I learned my lesson. Though she didn't complain, & i was young & nieve, but still.. I'm sure it wasn't that pleasent.
Yeah, when you go in for the kiss.. remember.. SLOWLY. & softly kiss with your lips. do this for a few seconds, then pull back & stare into her eyes. The go back in SLOWLY. Again, press your lips against hers & SLOWLY open your mouth & SLOWLY ease your tougue in.
Of course theres no set way to do this, but this is vague advice really, & you did ask. But the only thing that i think is important is to TAKE IT SLOWLY.
"slow & steady wins the race"
Oh, & when you're touguing her, don't do the washing machine & go round & round. explore. take your tougue in & out occasionally, etc.
It should come naturally after a minute or two. go with the flow. A really good make session shouldn''t involve any concious thought of what you're doing. just embrace the moment & let go to the pleasure.
hope thats aswered your question.
