Using your finger is easy, but hey she has fingers too. Your tongue would require a bit more effort, but hey you don't have to be a man to have a tongue. Making a girl reach orgasm through coitus should be the goal. But it is challenging, considering that you should not reach orgasm yourself until she reaches it. Nothing is as satisfying as pumping your girl and she says she's cumming...you continue pumping, and she says she's coming again...you continue pumping and she comes againg, again and again, continuously...until she finally requests to rest for awhile...that the cumming has made her so exhausted. Or that her flower is already too sore. Controlling yourself from reaching orgasm is key, you're biggest and hardest before your first ejaculation. Me I'd refrain from ejaculating until she's had enough, that her flower can't take anymore pumping, she's too exhausted from all the orgasms, or when her legs starts getting cramps, then I'll ejaculate on cue.
