It is not true that there are no sexual problems with Wellbutrin. Sexual problems are less common with Wellbutrin than with other SSRIs, but they do occur.
Ask your doctor if you can make a break with Wellbutrin for a month to see if the sexual problems disappear. Don't expect immediate effect, there can be a delay of some weeks before you see an improvement.
Maybe you do not need Wellbutrin any more, now when your financial problems are solved?
