So I am 18 and I'm not a virgin. My boyfriend wants to finger me/eat me out but that is like the only thing I haven't done. I guess I just want to know what it is like.
Any details or something anyone can tell me about this?

It will be aqward at first but the sooner u start and the more u do it the better u get and the better it feels

Really terrible!

What do you mean awkward?
I have done EVERYTHING else and those are the only things I was really wondering about.

Oh wow, why do you say it's really terrible?

Yes, why did someone say it was terrible? The first answering post from macman is accurate in that, just about anything is awkward until you've had some practice. For me, at first, the guys have no idea what to do. And I had no idea how to tell them they were doing it wrong. It took some practice and good communication.

Mouth, lungs (humming) and fingers, used correctly can be an extremely intense experience. Your boyfriend would do well to watch and feel your reactions, breathing, skin temperature and stuff while he tries different things. Don't be afraid to gently direct him. Don't be like my sister-in-law who after 6 years of marriage finally told him, "you know, you're licking in the wrong spot."

Trial and error are the only way you're going to find out for yourself what you like or don't like.

Make sure his hands are clean! My husband and I got a little frisky after changing a tire on the side of the highway... needless to say I got a yeast infection.

If what he does, doesn't work for you, try laying him on his back and then you placing yourself over his mouth, while he's licking away, you can place yourself in a position where you want to be licked, that way your in control and an orgasm is more likely.
