Don't think! It always goes weird and bad. Sex is more of a feeling than a thought. Go with the moment, like when you guys are close to one another and you look at him in his eyes and then touch him a little more intimately, then you guys start to kiss slowly/gently at first, then more heavily, with a little more tongue and more hungrily. More touching and more erotic places. After all this heated action, let your inhibitions and fears go and let the moment take you. Then the talking and communications, with the sensuality get's involved at the right time.

My suggestion is to keep it in your pants for now... But I say start with a make out session...
