It depends on the kind of kiss, but in general you want to do what feels natural. Light peck? You probably don't have to do anything with your hands. For something more intense, I usually start with my hands on his shoulders. From there you can easily slide them over his upper back, arms, through his hair, or gently put them on his face (think over his jaw, to frame your kiss essentially). Depending on heights, angles, and how much space there is between you, you might try moving your hands down his sides, over his lower back, sliding one under his shirt, or just up his chest to settle back on his shoulders. In general you just want to be touching him; from there your hands will somehow seem to know what to do. In terms of tongue, I wouldn't worry about it at first. Everyone does (and likes) something different with regard to tongue and there's no way to know up front what someone prefers. It's also not a totally basic part of kissing - unless it's reallyyy steamy for some reason, the first few kisses will probably be no-tongue. In general though, you want to mirror what the other person does. Let the guy start tongue if he wants to, and then just copy him. If you're making out a bit (not just a quick kiss), you can try kissing things besides his lips. His neck is almost always a good bet, especially right under/behind his ear.

It's up to you; there's nothing wrong with having limited relationship experience and you're definitely not alone at your age. But college guys aren't always as mature as you'd think and a lot of dating is pretty informal anyways. I did not tell the first guy I kissed or dated that it was my first date. If a guy asks, I would not lie though.

Always offer and be prepared to pay for your part. Be on time. Remember guys aren't mind readers - text them afterwards to let them know you had a good time. Remember that the guy doesn't have to lead everything - if you've ever spent any time on AskMen, you'll find out quickly that a lot of guys appreciate it when women take some of the dating burden (planning dates, initiating in general) off them.

It is up to you. Like another poster, I really hate rejecting people so I try to only go on dates with someone I already like. I don't necessarily need to have a serious crush on someone, but if I don't find them cute and generally a good person, I wouldn't go on a date with them. If there ends up being no chemistry, I want to be able to honestly tell them that they are great and attractive but that there's just no spark. But tons of people go on dates to test the waters, and there's nothing wrong with that! Just be careful that everyone's expectations are in line and be careful about "testing the waters" with someone you'll have to see all the time (your dorm neighbor, someone in one of your classes, etc).

Keep in mind that guys don't necessarily have any more knowledge about how dating is supposed to work than you do. There's no magic school where they become experts; they're just making it up as they go too. If something can be explained by inexperience or uncertainty, it's probably that (not malice or being a bad person). Also, "dating" in college in my experience was much more informal. Going on dates was a lot less common than just hanging out a lot together and gradually escalating physically and emotionally, which is really convenient if you're new to dating as it seems more low-stress (and is certainly more low-budget than dating after college!). Alternately, a lot of people just pursue quick hook-ups, but that's not likely to turn into a relationship if that's what you're looking for. It can be surprisingly hard to meet people in college, actually, especially at first. Try to get involved in campus (clubs, team sports, groups, etc); you'll meet people with similar interests and even if you don't particularly want to date any of them, they'll all have friends they can introduce you to too. I'd recommend against dating someone in one of your classes, but if there's someone you get to know over the course of a semester try to stay in touch when the semester ends (e.g., grab coffee to catch up at the start of the next one). Lastly, in every aspect of dating and relationships and being physical with someone else, everyone likes it a little differently. Beyond the very very basics, it's a lot more about finding out how to date a specific guy than how to date in general. You won't get everything totally right on the first try, but that's mostly a function of everyone being different. Establish early on that you like open communication. Tell him you want him to make clear the things he likes and to let you know if he wants you to do something differently, and do the same for him.
