2 mo isn't really a long time when you consider that a woman is only fertile for a max of 6 days all month. She should start charting to become familiar with her most fertile days. If you wear briefs switch to boxers, heat kills sperm. There are other precautions but obviously alcohol & supps can have a neg impact on sperm quality & production. If after 6 mo she is still not preggo it might be time to consult a fertility doc. A good source of info for increasing the odds of getting it done naturally is a site called webwomb (cheesy name but tons of info regarding charting). How to Choose the Sex of Your Baby is a great book too (& yes, you can actually influence your chances of having a boy or a girl - not 100% but better than 50/50). Hope that helps.
