1) Get a hair cut
2) Take a dump
3) take a shower and loofah my whole body
4) shave very closely
5) Brush, floss about three times
6) put on deodorant
7) take another dump. It's hard to be on a date when you need to fart.
8) put on very small amount of Cologne
9) whack off. You can not do this to early because you may reboot. It is the best prevention for blue balls, and you will not be a horny, puppy dog, tool. There is nothing better to turn a girl on than not drooling all over them.
10) carry a few new condoms. can't trust the old ones, and it's prudent to take more than one because you might have trouble getting it on. You also might not choose to bolt, and never call her again.
