Ooh, this is tricky to address over the interwebs, but here goes…

My current GF  had the same problem when we started dating. I was her second kiss ever. She was awful at making out at first. Two things will help you improve: enthusiasm and practice. But, to help before that, I’ll try and give you some pointers over the interwebs. (If you hadn’t emphasized your youth, I might have made some sort of snarky joke to the effect that I’d help you practice. But obviously I’m far too classy for that [plus I worry about who's reading this and the possibility of getting in trouble for propositioning a minor online].) Keep in mind that all my advice is just hints. They are not rules set in stone, but basic guidelines to get you started.

First helpful hit: what to do with your hands. This is tricky, and I recall many a makout session in my youth trying to figure out what the holy hell I was supposed to do with my hands. Never have I been so consious of the placement of these extremities. A good starting place would be one hand on his hip or his lower back, like you’re in a slow dance. The other hand LIGHTLY on his neck, placed like you’re pulling him in towards you. If the kiss gets passionate, you can lightly pull him into you like you’re afraid he’s going to stop. Speaking as a male, that is extremely hot. The hand on his neck probably shouldn’t stay there for more than a few minutes. After that, you can place it on his upper back and lightly pull him in that way as well. Don’t worry too much about this… once you get into it and your hands are already on him, the hands will tend to do their own thing. Just make sure that at least one hand is touching him at almost all times.

Now, we’re going to try and address the act of kissing. I’d like to add the caveat before starting this part of my guide that some of these things WILL NOT work properly if you have braces. You should know which ones (basically if I mention teeth and you have braces, don’t do that).

The beginning of a kiss should start a bit more modestly than the main part of the makeout session. Don’t ever have your tongue out if you’re more than an inch from him. The beginning of the kiss shouldn’t have any tongue involved. You can kiss open-mouthed, but the basic kiss will be something like putting your mouth open half an inch on his lips and closing it on his lips. Repeat this a bit for the prelude to making out.

Once you progress to tongue kissing, things get a bit trickier. I remember trying to figure out what my tongue should be doing during this. The very basic move to do in this is to meet his tongue during the kiss with a licking gesture with your tongue. A rookie mistake is to try and jam your tongue as far in the mouth as it can go. This generally isn’t an effective kissing technique. The best kissing I’ve ever had normally resides within half an inch inside someone’s mouth. The kissing should basically meet halfway.

If you’re looking for other things to do with your tongue during the kiss, you can try a few of my more advanced techniques, which are not guaranteed winners (I’ve had some girls absolutely love them, and some think it was a mistake on my part). Try running your tongue along his upper and lower lip. You can try running your tongue lightly along his upper front teeth. You could also try running your tongue along the length of his tongue. On occasion you can break away from the kiss just long enough to VERY LIGHTLY bite his lower lip and pull on it just a tiny amount. (Braces disclaimer here)

But a good makeout session involves more than just tongue wrestling. On occasion you should break away from the kiss to kiss his neck (or chest if you’re in an advanced makeout session). When kissing the body you generally don’t use your tongue unless you’re actually licking, which some people do enjoy.

OK, that’s what I’ve got at the moment. Sorry if my explanations are a bit hard to decipher without visuals. And remember, some of these techniques will work for you and your man, some may not. My hope is that they will.

But the most important thing is to relax and enjoy. If you get the urge to do something a little different, do it (with obvious exceptions, but I think you can figure those out). Explain to your BF that he should give advice on what is and isn’t good on your part. You’ll get better over time. Part of the fun of a new relationship is figuring out what floats each other’s boat. It’s one of those things where, if it’s a good relationship, occurs naturally.

Best of luck!

@SnippiesBlog - What can I say? My time as a man whore did give me some insight into the art of kissing. And I didn’t even get into my advanced techniques. 

@SnippiesBlog - And give other people the edge? I think not. I’m stockpiling these techniques just in case I decide to revert to a man whore again. Once I’m married I’ll donate them all to charity, but not until then.

@Karlalaley - Glad to hear it. Always nice to get validation on my mad skills.
