well there may be various reasons she doesnt want birth control such as the side effects etc... weight gain, circulation problems etc. i believe the male equivalent has none/ much fewer side effects. what i have read up on is that they are in the process of developing a male injection, and i think there may be already a male pill.... but the best option is to ask your gp who will advise you correctly! :) its only your business why you should choose to take charge of the birth control, and should be a respected decision! let us know the outcome, if there is any male option etc......
never heard of a pill for men but they should invent one soon. The best thing for men if they don't want to have kids and don't want to use condoms is get snipped but that is if you really don't want to have kids. Why doesn't she get on birth control?
