When starting out everyone should use only 1 light to light the subject - learn how to use one, then introduce more if & when you think they are needed later. Your avatar is a nice example of using one frontal light, and that harsh lights can work well on females too
2 frontal lights are common in shopping-centre photo booth type things - and it's a rubbish unnatural look IMO
Better, as MD says, to use from Key-light and the other on the background - certainly for white, but gels etc. can give a whole host of background colours
Oh, and remember to set your WB to 'flash'
