I'd love to try the spiderman kiss!! i was going to suggest it but i got beaten too it. I will DEFINATLY be doing that one once i get a girlfriend. probbaly not a first date thing though. I'll wait till the 3rd at least.
Thats such a fun rule to break!! I've only kissed 3 times and all of them were french (the kissing not the girls) so its the only type of kissing i know! as long as its mutual its a great way to first kiss.
anyway......more tips
vary your style. dont kiss the same way, it would become predictable. for example, dont save tounge for longer kisses. A very brief but very passionate kiss can keep her on her toes, girls normally expect short kisses to be same. the opposite is true, a make out session can involve lots of slow, soft little kisses all over her face with eskimo kisses to break things up. Instead of long french kissing.
I saw in a giftshop once a kissing set that looked awesome. What it was, was a box full of small jars (like little jam or marmlade) ones full of things like liquid chocolate, strawberry syrup etc and a small, flat paintbrush. the idea is that you paint your girlfriends lips with the strawberry syrup etc before kissing her. I thought it looked like amazing fun. It would be ideal at a picnic i reckon.
