Take your new panties out and take the labels off. Slowly roll them up your legs so your balls and cock are sat just above them.
Take a condom out of the packet and put a squeeze of toothpaste into the tip (2). Roll the condom over your tiny penis. I assume you've got an erection? Get some of the masking tape and cut a piece so that you can tie it round the base of your penis to secure that condom in place. Bet you're glad you shaved this morning now else that will pull a LOT of hairs out! (2)
