Wow, a LOT of good advice on here.
I don't want to reiterate what anyone already said, so I'll just add on here. First off, full disclosure: I was a virgin all the way until I graduate from college (like, literally, I got laid for the first time a week after I knew I'd be graduating). At the time, I was (a) an AFC, and (b) trying to wait until marriage to have sex (thinking women would find it more respectable, i.e. see (a) again.)
You would think telling girls you were a virgin would be a deterrent (lord knows I did). Turns out, it just made girls want to try harder to de-virginize me. Were I not such an AFC at the time I would've probably banged at least 4 or 5 chicks in my first college year.
Anyway... here are a few tips courtesy of me, that I found to be effective in girls showing interest in wanting to bone me:
1. When you first meet them, DON'T GET THEIR NUMBER. Dude, they're on campus, so you're going to run into them again. Plus, EVERY GUY on campus has the same plan - meet lots of girls, get numbers - and they're hip to it. If you talk to them, make them laugh, smile, etc. and then DON'T ask for their info, they'll be DYING to give it to you the next time they see you.
2. Like someone said earlier, no handshakes and no "hi, how are you, my name's so and so's". In fact, you want to WAIT for them to ask you YOUR name. Ask their name if you must, then say, "oh, nice to meet you, Susie. So, where are you from." If they ask your name, it means they want to know more about you; if they don't, you just saved yourself some time. (Some people on here may balk at this, but I've dated more girls who asked me my name than those that initially didn't. Just going based on my experience.)
3. Get really good at a subject, then ask any of the girls if they need a study partner. Then, during your study sessions, in between all that book knowledge when you're having a conversation with her, tell her about the aspects of your life that are interesting: wild trips you've gone on, parties you've thrown, hobbies that she may have never heard of... these things will get her mind thinking about what an interesting person you are. Then, she'll start wondering how she could be privy to some of these wonderful adventures (which, in her mind, she could only do... if she's DATING you!)
If you go this route, it's very important not to actually INVITE her to do anything. Once you've seen her a few study sessions, you should notice her starting to ask if you two can hang out after the session is over. I had a girl dang near trying to come up to my room by herself just wanting to "hang out 'cause she happened to be near my dorm." (And I was out of town - dang it!)
4. Go to all school dances and show off your moves. Be the life of the party on the floor - you want every girl there wanting to wonder how you move so well, and when they can move along with you. I rarely ever asked girls to dance with me in college, but my dance moves were so good they would come up to me and freak the shiznit out of me!
5. Don't be in a rush. Most of the girls you're meeting now will be there for the next 4 year (or, at the very least, this semester, lol). The patience game is in your favor here.
6. Lastly, a quick note about the girls that say "I have a boyfriend back home." For the most part, this fact will be true in August; by homecoming, though, they will not have seen him regularly for 2 months, and will be wanting closer male affection. During those two months, do NOT try to go after these girls. Befriend them if you must, but have very little contact with them. Make sure they see you around campus in a good mood, having a good time, or enjoying life in general. Trust they'll notice it, and when they break up with their back-home-boo by homecoming, wait for her to tell you the boo-hoo-break up story before making a move. If they offer up the story to you, there's a good chance it means they're interested in what you have to offer. Don't fear being the rebound guy - even if you are, rebound guys get laid. And if it's been 2 months of no sex for her, you'll get laid GOOD :rockon:
Hope this helps!
