lol- if you send them to a friends house your fine, but honestly- i think your fine sending them to your house as well... I dont think the man is watching your everymove, I am assuming your a relatively small fish in this big pond- if you were ordering 100 seeds and an arsenol of soviet weapons they might look twice, but if your just some guy ordering 10 seeds they aren't going to be looking for you or kicking your door down. sending them to a friends house as a precaution is a good idea. Pay cash or with a gift card is also a great idea. but theres not a lot you can do to guarentee females- if its your first grow just cross your fingers, if your experienced and sick of dealing with males- then clone your females and make mother plants-
best of luck
