How Do I Tell My Boyfriend of Two Months

First off, you need to decide if your boyfriend is "not good at oral sex" or whether you "still enjoy it". Your question is a little contradictory.

Is he not good at oral sex simply because you don't have an orgasm?

I know it's hard for you being a virgin, but you need to express your thoughts and feelings to him about sex, your body and what you like. He's not a mind reader so you need to let him know certain things. If you prefer him to finger you, then tell him. Don't do it in a condescending manner or put him down, just let him know. I guarantee you he just wants to make you happy.

If he doesn't know how to find your G-spot (and assuming you do), show him where it is. Move his hands/mouth around so he does/know what you like.

Everyone likes different things (as you'll find out with other sexual partners) and has different experiences. You're the only one who knows what you like so make sure to communicate that to your bf.

Well you shouldn't have lied in the first place! But since you have yourself in this predicament why don't you try changing things up a bit. Maybe try toys or something different. And anymore if he asks you tell him the truth. Truth and honesty is the most important thing in a relationship. After you lose that you lose it all. So stop lying, start telling the truth, and talk about how you can spice things up without losing your virginity! No matter what you do though, Stay safe! :)

Tough questions, my last relationship I told him. And he turned sex and foreplay into a chore! He would just do it for hours and would get so frustrated because I couldn't orgasm. It was a mood killer lol.

tell him or maybe watch a porno together and point things out that may spice things up.

Well I think you should definitely tell him because otherwise not telling him is kind of worse because he probably thinks he is doing well and then if he finds out much later on that you were lying then he will feel like a fool. So in the long run it is best you tell him. Also do you really want to go on lying about what it feels like and not feeling fully satisfied not only does he deserve the truth you deserve to be pleasured just as much as he is.

I think don't say outright you're crap at oral or whatever but do things like this:
whenever he does something that feels really good then show it moan, tell him, compliment it - guys will generally rememeber your best reactions and hopefully he will continue whatever he did right

or maybe try fingering yourself with him so he knows where your g spot is

and don't be afraid when he;s down there to guide him by saying things like a little to the left or omg that's good etc just tell him when he does good.

but don't say he can't do it because that will probably ruin his confidence just subtle criticism will work and a bit of guidance and lots and lots of practice, because he will get better :)
