Don't swing your tongue round and round like a windmill.
Explore lightly, don't drill your way through.
Start to french kiss your partner as you normally would.Then slowly and GENTLY suck on their bottom lip. They'll love it.
Lick your partner's lips with the tip of your tongue.
Get his/her tongue in your mouth and hold it there by gently sucking on it.Then slowly withdraw your mouth sucking his/her tongue the whole way back.
